Nanocellulose sensors: 3D printed and biocompatible

I do like to keep up with nanocellulose doings, especially when there’s some Canadian involvement, and an October 8, 2019 news item on Nanowerk alerted me to a newish application for the product,

Physiological parameters in our blood can be determined without painful punctures. Empa researchers are currently working with a Canadian team to develop flexible, biocompatible nanocellulose sensors that can be attached to the skin. The 3D-printed analytic chips made of renewable raw materials will even be biodegradable in future.

The idea of measuring parameters that are relevant for our health via the skin has already taken hold in medical diagnostics. Diabetics, for example, can painlessly determine their blood sugar level with a sensor instead of having to prick their fingers.

An October 8, 2019 Empa (Swiss Federal Laboratories for Materials Science and Technology) press release, which originated the news item, provides more detail,

A transparent foil made of wood

Nanocellulose is an inexpensive, renewable raw material, which can be obtained in form of crystals and fibers, for example from wood. However, the original appearance of a tree no longer has anything to do with the gelatinous substance, which can consist of cellulose nanocrystals and cellulose nanofibers. Other sources of the material are bacteria, algae or residues from agricultural production. Thus, nanocellulose is not only relatively easy and sustainable to obtain. Its mechanical properties also make the “super pudding” an interesting product. For instance, new composite materials based on nanocellulose can be developed that could be used as surface coatings, transparent packaging films or even to produce everyday objects like beverage bottles.

Researchers at Empa’s Cellulose & Wood Materials lab and Woo Soo Kim from the Simon Fraser University [SFU] in Burnaby, Canada, are also focusing on another feature of nanocellulose: biocompatibility. Since the material is obtained from natural resources, it is particularly suitable for biomedical research.

With the aim of producing biocompatible sensors that can measure important metabolic values, the researchers used nanocellulose as an “ink” in 3D printing processes. To make the sensors electrically conductive, the ink was mixed with silver nanowires. The researchers determined the exact ratio of nanocellulose and silver threads so that a three-dimensional network could form.

Just like spaghetti – only a wee bit smaller

It turned out that cellulose nanofibers are better suited than cellulose nanocrystals to produce a cross-linked matrix with the tiny silver wires. “Cellulose nanofibers are flexible similar to cooked spaghetti, but with a diameter of only about 20 nanometers and a length of just a few micrometers,” explains Empa researcher Gilberto Siqueira.

The team finally succeeded in developing sensors that measure medically relevant metabolic parameters such as the concentration of calcium, potassium and ammonium ions. The electrochemical skin sensor sends its results wirelessly to a computer for further data processing. The tiny biochemistry lab on the skin is only half a millimeter thin.

While the tiny biochemistry lab on the skin – which is only half a millimeter thin – is capable of determining ion concentrations specifically and reliably, the researchers are already working on an updated version. “In the future, we want to replace the silver [nano] particles with another conductive material, for example on the basis of carbon compounds,” Siqueira explains. This would make the medical nanocellulose sensor not only biocompatible, but also completely biodegradable.

I like the images from Empa better than the ones from SFU,

SFU produced a news release about this work back in February 2019. Again, I prefer what the Swiss have done because they’re explaining/communicating the science, as well as , communicating benefits. From a February 13, 2019 SFU news release (Note: Links have been removed),

Simon Fraser University and Swiss researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be used and disposed of without contaminating the environment. Their research has been published as the cover story in the February issue of the journal Advanced Electronic Materials.

SFU professor Woo Soo Kim is leading the research team’s discovery, which uses a wood-derived cellulose material to replace the plastics and polymeric materials currently used in electronics.

Additionally, 3D printing can give flexibility to add or embed functions onto 3D shapes or textiles, creating greater functionality.

“Our eco-friendly, 3D-printed cellulose sensors can wirelessly transmit data during their life, and then can be disposed without concern of environmental contamination,” says Kim, a professor in the School of Mechatronic Systems Engineering. The SFU research is being carried out at PowerTech Labs in Surrey, which houses several state-of-the-art 3D printers used to advance the research.

“This development will help to advance green electronics. For example, the waste from printed circuit boards is a hazardous source of contamination to the environment. If we are able to change the plastics in PCB to cellulose composite materials, recycling of metal components on the board could be collected in a much easier way.”

Kim’s research program spans two international collaborative projects, including the latest focusing on the eco-friendly cellulose material-based chemical sensors with collaborators from the Swiss Federal Laboratories for Materials Science.

He is also collaborating with a team of South Korean researchers from the Daegu Gyeongbuk Institute of Science and Technology’s (DGIST)’s department of Robotics Engineering, and PROTEM Co Inc, a technology-based company, for the development of printable conductive ink materials.

In this second project, researchers have developed a new breakthrough in the embossing process technology, one that can freely imprint fine circuit patterns on flexible polymer substrate, a necessary component of electronic products.

Embossing technology is applied for the mass imprinting of precise patterns at a low unit cost. However, Kim says it can only imprint circuit patterns that are imprinted beforehand on the pattern stamp, and the entire, costly stamp must be changed to put in different patterns.

The team succeeded in developing a precise location control system that can imprint patterns directly resulting in a new process technology. The result will have widespread implications for use in semiconductor processes, wearable devices and the display industry.

This paper was made available online back in December 2018 and then published in print in February 2019. As to why there’d be such large gaps between the paper’s publication dates and the two institution’s news/press releases, it’s a mystery to me. In any event, here’s a link to and a citation for the paper,

Sadly I was not able to post the information about Dr. Gibbs’s more informal talk last night (Sept. 3, 2019) which was a special event with Café Scientifique but I do have a link to a website encouraging anyone who wants to help get science on the 2019 federal election agenda, Vote Science. P.S. I’m sorry I wasn’t able to post this in a more timely fashion.

Transmissions; a multimedia installation in Vancouver, September 6 -28, 2019

Here’s a description for the multimedia installation, Transmissions, in the August 28, 2019 Georgia Straight article by Janet Smith,

Lisa Jackson is a filmmaker, but she’s never allowed that job description to limit what she creates or where and how she screens her works.

The Anishinaabe artist’s breakout piece was last year’s haunting virtual-reality animation Biidaaban: First Light. In its eerie world, one that won a Canadian Screen Award, nature has overtaken a near-empty, future Toronto, with trees growing through cracks in the sidewalks, vines enveloping skyscrapers, and people commuting by canoe.

All that and more has brought her here, to Transmissions, a 6,000-square-foot, immersive film installation that invites visitors to wander through windy coastal forests, by hauntingly empty glass towers, into soundscapes of ancient languages, and more.

Through the labyrinthine multimedia work at SFU [Simon Fraser University] Woodward’s, Jackson asks big questions—about Earth’s future, about humanity’s relationship to it, and about time and Indigeneity.

Simultaneously, she mashes up not just disciplines like film and sculpture, but concepts of science, storytelling, and linguistics [emphasis mine].

“The tag lines I’m working with now are ‘the roots of meaning’ and ‘knitting the world together’,” she explains. “In western society, we tend to hive things off into ‘That’s culture. That’s science.’ But from an Indigenous point of view, it’s all connected.”

Transmissions is split into three parts, with what Jackson describes as a beginning, a middle, and an end. Like Biidaaban, it’s also visually stunning: the artist admits she’s playing with Hollywood spectacle.

Without giving too much away—a big part of the appeal of Jackson’s work is the sense of surprise—Vancouver audiences will first enter a 48-foot-long, six-foot-wide tunnel, surrounded by projections that morph from empty urban streets to a forest and a river. Further engulfing them is a soundscape that features strong winds, while black mirrors along the floor skew perspective and play with what’s above and below ground.

“You feel out of time and space,” says Jackson, who wants to challenge western society’s linear notions of minutes and hours. “I want the audience to have a physical response and an emotional response. To me, that gets closer to the Indigenous understanding. Because the Eurocentric way is more rational, where the intellectual is put ahead of everything else.”

Viewers then enter a room, where the highly collaborative Jackson has worked with artist Alan Storey, who’s helped create Plexiglas towers that look like the ghost high-rises of an abandoned city. (Storey has also designed other components of the installation.) As audience members wander through them on foot, projections make their shadows dance on the structures. Like Biidaaban, the section hints at a postapocalyptic or posthuman world. Jackson operates in an emerging realm of Indigenous futurism.

The words “science, storytelling, and linguistics” were emphasized due to a minor problem I have with terminology. Linguistics is defined as the scientific study of language combining elements from the natural sciences, social sciences, and the humanities. I wish either Jackson or Smith had discussed the scientific element of Transmissions at more length and perhaps reconnected linguistics to science along with the physics of time and space, as well as, storytelling, film, and sculpture. It would have been helpful since it’s my understanding, Transmissions is designed to showcase all of those connections and more in ways that may not be obvious to everyone. On the plus side, perhaps the tour, which is part of this installation experience includes that information.

I have a bit .more detail (including logistics for the tours) from the SFU Events webpage for Transmissions,

TRANSMISSIONS is a three-part, 6000 square foot multimedia installation by award-winning Anishinaabe filmmaker and artist Lisa Jackson. It extends her investigation into the connections between land, language, and people, most recently with her virtual reality work Biidaaban: First Light.

Projections, sculpture, and film combine to create urban and natural landscapes that are eerie and beautiful, familiar and foreign, concrete and magical. Past and future collide in a visceral and thought-provoking journey that questions our current moment and opens up the complexity of thought systems embedded in Indigenous languages. Radically different from European languages, they embody sets of relationships to the land, to each other, and to time itself.

Transmissions invites us to untether from our day-to-day world and imagine a possible future. It provides a platform to activate and cross-pollinate knowledge systems, from science to storytelling, ecology to linguistics, art to commerce. To begin conversations, to listen deeply, to engage varied perspectives and expertise, to knit the world together and find our place within the circle of all our relations.

Her Story: Canadian Women Scientists (short film subjects); Sept. 13 – 14, 2019

Curiosity Collider, producer of art/science events in Vancouver, is presenting a film series featuring Canadian women scientists, according to an August 27 ,2019 press release (received via email),

Her Story: Canadian Women Scientists,” a film series dedicated to sharing the stories of Canadian women scientists, will premiere on September 13th and 14th at the Annex theatre. Four pairs of local filmmakers and Canadian women scientists collaborated to create 5-6 minute videos; for each film in the series, a scientist tells her own story, interwoven with the story of an inspiring Canadian women scientist who came before her in her field of study.

Produced by Vancouver-based non-profit organization Curiosity Collider, this project was developed to address the lack of storytelling videos showcasing remarkable women scientists and their work available via popular online platforms. “Her Story reveals the lives of women working in science,” said Larissa Blokhuis, curator for Her Story. “This project acts as a beacon to girls and women who want to see themselves in the scientific community. The intergenerational nature of the project highlights the fact that women have always worked in and contributed to science.

This sentiment was reflected by Samantha Baglot as well, a PhD student in neuroscience who collaborated with filmmaker/science cartoonist Armin Mortazavi in Her Story. “It is empowering to share stories of previous Canadian female scientists… it is empowering for myself as a current female scientist to learn about other stories of success, and gain perspective of how these women fought through various hardships and inequality.”

When asked why seeing better representation of women in scientific work is important, artist/filmmaker Michael Markowsky shared his thoughts. “It’s important for women — and their male allies — to question and push back against these perceived social norms, and to occupy space which rightfully belongs to them.” In fact, his wife just gave birth to their first child, a daughter; “It’s personally very important to me that she has strong female role models to look up to.” His film will feature collaborating scientist Jade Shiller, and Kathleen Conlan – who was named one of Canada’s greatest explorers by Canadian Geographic in 2015.

Other participating filmmakers and collaborating scientists include: Leslie Kennah (Filmmaker), Kimberly Girling (scientist, Research and Policy Director at Evidence for Democracy), Lucas Kavanagh and Jesse Lupini (Filmmakers, Avocado Video), and Jessica Pilarczyk (SFU Assistant Professor, Department of Earth Sciences).

This film series is supported by Westcoast Women in Engineering, Science and Technology (WWEST) and Eng.Cite. The venue for the events is provided by Vancouver Civic Theatres.

Event Information

Screening events will be hosted at Annex (823 Seymour St, Vancouver) on September 13th and 14th [2019].

ETA September 4, 2019 at 1607 hours PDT: That last comment is even truer than I knew when I published earlier. I missed a Vancouver event, Maker Faire Vancouver will be hosted at Science World on Saturday, September 14. Here’s a little more about it from a Sept. 3, 2019 at Science World at Telus Science World blog posting,

Earlier last month [August 2019?], surgeons at St Paul’s Hospital performed an ankle replacement for a Cloverdale resident using a 3D printed bone. The first procedure of its kind in Western Canada, it saved the patient all of his ten toes — something doctors had originally decided to amputate due to the severity of the motorcycle accident.

Maker Faire Vancouver Co-producer, John Biehler, may not be using his 3D printer for medical breakthroughs, but he does see a subtle connection between his home 3D printer and the Health Canada-approved bone.

“I got into 3D printing to make fun stuff and gadgets,” John says of the box-sized machine that started as a hobby and turned into a side business. “But the fact that the very same technology can have life-changing and life-saving applications is amazing.”

When John showed up to Maker Faire Vancouver seven years ago, opportunities to access this hobby were limited. Armed with a 3D printer he had just finished assembling the night before, John was hoping to meet others in the community with similar interests to build, experiment and create. Much like the increase in accessibility to these portable machines has changed over the years—with universities, libraries and makerspaces making them readily available alongside CNC Machines, laser cutters and more — John says the excitement around crafting and tinkering has skyrocketed as well.

“The kind of technology that inspires people to print a bone or spinal insert all starts at ground zero in places like a Maker Faire where people get exposed to STEAM,” John says …

… From 3D printing enthusiasts like John to knitters, metal artists and roboticists, this full one-day event [Maker Faire Vancouver on Saturday, September 14, 2019] will facilitate cross-pollination between hobbyists, small businesses, artists and tinkerers. Described as part science fair, part county fair and part something entirely new, Maker Faire Vancouver hopes to facilitate discovery and what John calls “pure joy moments.”

Hopefully that’s it.

Frugal science, foldable microscopes, and curiosity: a talk on June 3, 2019 at Simon Fraser University (Burnaby, Canada) … it’s in Metro Vancouver

This is the second frugal science item* I’m publishing today (May 29, 2019) which means that I’ve gone from complete ignorance on the topic to collecting news items about it. Manu Prakash, the developer behind a usable paper microscope than can be folded and kept in your pocket, is going to be giving a talk locally according to a May 28, 2019 announcement (received via email) from Simon Fraser University’s (SFU) Faculty of Science,

On June 3rd [2019], at 7:30 pmManu Prakash from Stanford University will give the Herzberg Public Lecture in conjunction with this year’s Canadian Association of Physicists (CAP) conference that the department is hosting. Dr. Prakash’s lecture is entitled “Frugal Science in the Age of Curiosity”. Tickets are free and can be obtained through Eventbrite: https://t.co/WNrPh9fop5 . 

This presentation will be held at the Shrum Science Centre Chemistry C9001 Lecture Theatre, Burnaby campus (instead of the Diamond Family Auditorium).

There’s a synopsis of the talk on the Herzbergy Public Lecture: Frugal Science in the Age of Curiosity webpage,

Science faces an accessibility challenge. Although information/knowledge is fast becoming available to everyone around the world, the experience of science is significantly limited. One approach to solving this challenge is to democratize access to scientific tools. Manu Prakash believes this can be achieved via “Frugal science”; a philosophy that inspires design, development, and deployment of ultra-affordable yet powerful scientific tools for the masses. Using examples from his own work (Foldscope: one-dollar origami microscope, Paperfuge: a twenty-cent high-speed centrifuge), Dr. Prakash will describe the process of identifying challenges, designing solutions, and deploying these tools globally to enable open ended scientific curiosity/inquiries in communities around the world. By connecting the dots between science education, global health and environmental monitoring, he will explore the role of “simple” tools in advancing access to better human and planetary health in a resource limited world.

If you’re curious there is a Foldscope website where you can find out more and/or get a Foldscope for yourself.

In addition to the talk, there is a day-long workshop for teachers (as part of the 2019 CAP Congress) with Dr. Donna Strickland the University of Waterloo researcher who won the 2018 Nobel Prize for physics. If you want to learn how to make a Foldscope, t here is also a one hour session for which you can register separately from the day-long event,. (I featured Strickland and her win in an October 3, 2018 posting.)

Getting back to the main event. Dr. Prakash’s evening talk, you can register here.

*ETA May 29, 2019 at 1120 hours PDT: My first posting on frugal science is Frugal science: ancient toys for state-of-the-art science. It’s about a 3D printable centrifuge based on a toy known (in English) as a whirligig.
