NANOART Research Tool offers affordable paint analysis

There’s some encouraging news for art conservators and authenticators, an affordable nanotech-based kit for greater accuracy analyzing ancient (or old)  paint is one step closer according to a Jan. 11, 2016 notice on CORDIS,

Developed through the EU-funded NANOART project, the new testing kit has already been applied to identify binders such as collagen and ovalbumin in ancient paint, not only in model samples painted in the lab but also in real samples collected from works of art.

‘Once fully completed, our new tool will be made available to conservation scientists from around the world at an affordable cost (an assay can cost around EUR 0.5 per target), which will facilitate greater knowledge about historical works of art and help international museums, restoration art studios and laboratories to plan the best conservation and preventive strategies,’ explains NANOART project coordinator Dr Jesus de la Fuente from the CSIC/University of Zaragoza, Spain.

In addition, the sensitiveness of the project’s new nanotechnology-based methods means that smaller samples are required to be taken from the artwork for analysis. This in itself will help to better preserve our cultural heritage.

In order to characterise ancient paints, experts have often relied on conventional molecular biology methodologies that were developed decades ago. The concept behind the NANOART project was that these techniques could be substituted by more sensitive, inexpensive and faster techniques that take advantage of emerging nanotechnologies.

Furthermore, conventional methods – apart from being expensive – are also only available at a few laboratories, and require specialised personnel and equipment. A key objective of the NANOART project has been to address the cost issue by applying techniques developed for clinical diagnosis. In this way, the project is also highly original as it aims to take latest developments in clinical medicine and apply them to the conservation and preservation of cultural heritage.

‘The innovative nature of the project is also denoted by the fact that there is currently no method or kit available that can be easily used at point-of-care to analyse paints without requiring expensive equipment and extensive training,’ says Ana Claro, research fellow from the INA/University of Zaragoza. ‘With the NANOART kit, the final user will be able to conduct an affordable analysis (in some cases at the cost of only a few euros) by simply following the instructions. Within a four-hour period, the results will be available.’

The potential opportunities opened up by the new analytical nanotechnology are huge. For example, developed in parallel with the NANOART kit, a spin-off company called NanoImmunotech has been launched in order to develop devices to detect bacterial infection in meat using the same technology as used in NANOART.

‘This opens our technology to other applications far from cultural heritage applications,’ says de la Fuente. ‘However, we would like to continue further developing novel uses of NANOART technology for other applications in cultural heritage, and our next step will be to look for funding to develop an even more user friendly device.’

This announcement comes just as the NANOART project is scheduled to be completed (Jan. 31, 2016) according to its webpage on CORDIS.

For those with Spanish language skills, there’s this Jan. 11, 2016 news item on the Catalunya Vanguardista website (I believe the English language version above is a machine translation with this being the original text),

Nanotecnología para analizar pinturas históricas de forma barata y precisa

Empleando nanotecnologías, se ha creado un equipo de diagnóstico clínico destinado a analizar capas de pintura antiguas que podría ahorrar costes a los profesionales de la conservación y permitirles alcanzar mayor precisión.

Cordis / El nuevo equipo de ensayo, desarrollado mediante el proyecto financiado con fondos europeos NANOART, ya se ha empleado en la identificación de aglutinantes como el colágeno y la ovoalbúmina en pinturas históricas. Además, los resultados se han obtenido tanto con muestras pintadas en el laboratorio como con otras extraídas de obras de arte.

«Una vez completemos su desarrollo, nuestra herramienta quedará a disposición de científicos de todo el mundo dedicados a la conservación por un módico precio (cada ensayo costará cerca de medio euro por objetivo). De este modo se obtendrá un conocimiento más profundo sobre las obras de arte históricas y tanto museos como talleres de restauración y laboratorios podrán plantear las estrategias de conservación y prevención idóneas», explicó el coordinador del proyecto, el Dr. Jesús de la Fuente del Instituto de Ciencia de los Materiales —centro mixto dependiente del CSIC y la Universidad de Zaragoza (España)—.Además, la sensibilidad ofrecida por los métodos nanotecnológicos propuestos por el proyecto permite extraer muestras de menor tamaño de las obras de arte, lo cual contribuirá a conservar mejor el patrimonio cultural.Para caracterizar pinturas antiguas, hasta ahora los expertos solían emplear metodologías convencionales de la biología molecular desarrolladas hace decenios. La propuesta del proyecto NANOART pasa por sustituir estas técnicas por otras más sensibles, baratas y rápidas que se valen de las nanotecnologías emergentes.

Es más, los métodos convencionales, además de resultar caros, sólo están a disposición de unos pocos laboratorios que cuentan con equipos y personal especializados. NANOART se propuso sobre todo abaratar los costes mediante el empleo de técnicas de diagnóstico del ámbito clínico. La originalidad de este planteamiento es notoria, pues aprovecha los últimos progresos logrados en medicina clínica para aplicarlos a la conservación y la protección del patrimonio cultural.

«La naturaleza innovadora del proyecto también obedece a la carencia hoy en día de un método o equipo que pueda emplearse con facilidad in situ para analizar pinturas sin necesidad de equipos caros ni formación exhaustiva», afirmó Ana Claro, investigadora del INA de la Universidad de Zaragoza. «Gracias al equipo de NANOART, el usuario final podrá ejecutar ensayos asequibles, en algunos casos por valor de tan sólo unos pocos euros, siguiendo las instrucciones proporcionadas. Los resultados estarán disponibles en cuatro horas».

Las oportunidades que ofrece la nueva nanotecnología analítica son enormes. Por ejemplo, la empresa derivada NanoImmunotech se ha puesto en marcha en paralelo al desarrollo del equipo de NANOART para que cree servicios con los que detectar infecciones bacterianas en la carne mediante los mismos métodos empleados por el proyecto en el ámbito del arte.

«De esta forma se amplían las aplicaciones de la tecnología a otros campos muy alejados del patrimonio cultural», afirmó de la Fuente. «No obstante, seguiremos indagando en nuevos usos de la tecnología de NANOART relacionados con el patrimonio cultural y procederemos ya a buscar fuentes de financiación que nos permitan crear un dispositivo aún más fácil de usar».

I expect the folks at the Canadian Conservation Institute (CCI) and other such insitutions are keeping a close eye on developments of this nature. The institute was mentioned here in the context of a series I wrote on attempts to authenticate a painting, Autumn Harbour, as a Lawren Harris (one of Canada’s Group of Seven painters). My July 14, 2014 post was devoted to a response from Marie-Claude Corbeil to a query about scientific investigation of visual art,

… [the response],

The Canadian Conservation Institute (CCI) has been conducting research into the materials and techniques of Canadian artists (mainly 20th-century artists) since the early 1990s. Databases were created for each artists. At the moment CCI has no such database on Harris.

The CCI is the only institution in Canada carrying out this kind of research. I would add that European conservation institutes or laboratories have a long tradition of conducting this type of research focusing mainly on European art, basically because many were created long before North-American conservation institutes or laboratories were established.

I was quite fascinated by the whole thing and wrote a four-part series about Autumn Harbour, Lawren Harris, and much more, as well as, the July 14, 2014 post, which has links to the Autumn Harbour series along with the response from the CCI and links to articles recommended by Corbeil.

Canada and some graphene scene tidbits

For a long time It seemed as if every country in the world, except Canada, had some some sort of graphene event. According to a July 16, 2015 news item on Nanotechnology Now, Canada has now stepped up, albeit, in a peculiarly Canadian fashion. First the news,

Mid October [Oct. 14 -16, 2015], the Graphene & 2D Materials Canada 2015 International Conference & Exhibition (www.graphenecanada2015.com) will take place in Montreal (Canada).

I found a July 16, 2015 news release (PDF) announcing the Canadian event on the lead organizer’s (Phantoms Foundation located in Spain) website,

On the second day of the event (15th October, 2015), an Industrial Forum will bring together top industry leaders to discuss recent advances in technology developments and business opportunities in graphene commercialization.
At this stage, the event unveils 38 keynote & invited speakers. On the Industrial Forum 19 of them will present the latest in terms of Energy, Applications, Production and Worldwide Initiatives & Priorities.

Plenary:
Gary Economo (Grafoid Inc., Canada)
Khasha Ghaffarzadeh (IDTechEx, UK)
Shu-Jen Han (IBM T.J. Watson Research Center, USA)
Bor Z. Jang (Angstron Materials, USA)
Seongjun Park (Samsung Advanced Institute of Technology (SAIT), Korea)
Chun-Yun Sung (Lockheed Martin, USA)

Parallel Sessions:
Gordon Chiu (Grafoid Inc., Canada)
Jesus de la Fuente (Graphenea, Spain)
Mark Gallerneault (ALCERECO Inc., Canada)
Ray Gibbs (Haydale Graphene Industries, UK)
Masataka Hasegawa (AIST, Japan)
Byung Hee Hong (SNU & Graphene Square, Korea)
Tony Ling (Jestico + Whiles, UK)
Carla Miner (SDTC, Canada)
Gregory Pognon (THALES Research & Technology, France)
Elena Polyakova (Graphene Laboratories Inc, USA)
Federico Rosei (INRS–EMT, Université du Québec, Canada)
Aiping Yu (University of Waterloo, Canada)
Hua Zhang (MSE-NTU, Singapore)

Apart from the industrial forum, several industry-related activities will be organized:
– Extensive thematic workshops in parallel (Standardization, Materials & Devices Characterization, Bio & Health and Electronic Devices)
– An exhibition carried out with the latest graphene trends (Grafoid, RAYMOR NanoIntegris, Nanomagnetics Instruments, ICEX and Xerox Research Centre of Canada (XRCC) already confirmed)
– B2B meetings to foster technical cooperation in the field of Graphene

It’s still possible to contribute to the event with an oral presentation. The call for abstracts is open until July, 20 [2015]. [emphasis mine]

Graphene Canada 2015 is already supported by Canada’s leading graphene applications developer, Grafoid Inc., Tourisme Montréal and Université de Montréal.

This is what makes the event peculiarly Canadian: multiculturalism, anyone? From the news release,

Organisers: Phantoms Foundation www.phantomsnet.net & Grafoid Foundation (lead organizers)

CEMES/CNRS (France) | Grafoid (Canada) | Catalan Institute of Nanoscience and Nanotechnology – ICN2 (Spain) | IIT (Italy) | McGill University, Canada | Texas Instruments (USA) | Université Catholique de Louvain (Belgium) | Université de Montreal, Canada

It’s billed as a ‘Canada Graphene 2015’ and, as I recall, these types of events don’t usually have so many other countries listed as organizers. For example, UK Graphene 2015 would have mostly or all of its organizers (especially the leads) located in the UK.

Getting to the Canadian content, I wrote about Grafoid at length tracking some of its relationships to companies it owns, a business deal with Hydro Québec, and a partnership with the University of Waterloo, and a nonrepayable grant from the Canadian federal government (Sustainable Development Technology Canada [SDTC]) in a Feb. 23, 2015 posting. Do take a look at the post if you’re curious about the heavily interlinked nature of the Canadian graphene scene and take another look at the list of speakers and their agencies (Mark Gallerneault of ALCERECO [partially owned by Grafoid], Carla Miner of SDTC [Grafoid received monies from the Canadian federal department],  Federico Rosei of INRS–EMT, Université du Québec [another Quebec link], Aiping Yu, University of Waterloo [an academic partner to Grafoid]). The Canadian graphene community is a small one so it’s not surprising there are links between the Canadian speakers but it does seem odd that Lomiko Metals is not represented here. Still, new speakers have been announced since the news release (e.g., Frank Koppens of ICFO, Spain, and Vladimir Falko of Lancaster University, UK) so  time remains.

Meanwhile, Lomiko Metals has announced in a July 17, 2015 news item on Azonano that Graphene 3D labs has changed the percentage of its outstanding shares affecting the percentage that Lomiko owns, amid some production and distribution announcements. The bit about launching commercial sales of its graphene filament seems more interesting to me,

On March 16, 2015 Graphene 3D Lab (TSXV:GGG) (OTCQB:GPHBF) announced that it launched commercial sales of its Conductive Graphene Filament for 3D printing. The filament incorporates highly conductive proprietary nano-carbon materials to enhance the properties of PLA, a widely used thermoplastic material for 3D printing; therefore, the filament is compatible with most commercially available 3D printers. The conductive filament can be used to print conductive traces (similar to as used in circuit boards) within 3D printed parts for electronics.

So, that’s all I’ve got for Canada’s graphene scene.
