Maskwriting facilities at 4D Labs and some bottom-up engineering news

Following up on yesterday’s news from Simon Fraser University (SFU), I gather that maskwriting has to do with fabricating nanoscale materials and the facility they will be building for their 4D Labs will allow them to create nanoscale structures that measure less than 20 nanometres.

“This capability will eventually be as key to nanoscale materials fabrication as the photocopier is to information dissemination,” explains [Byron] Gates, 4D LABS’ director of nanofabrication. “With our new maskwriting facility, we’ll be able to fabricate the next generation of technologies, particularly in the fields of alternative energy and biomedical engineering.”

Local companies will not have send off to Alberta to get this work done and it will give 4D Labs some revenue.  Given that universities are under pressure these days to develop new revenue streams, this has to be good news.

Meanwhile, scientists at the California Institute of Technology (Caltech) have recently published a paper describing their work on bottom-up engineering of DNA ‘seeds’. The two main approaches to engineering in nanotechnology (and this is simplified) are top-down and bottom-up. Traditional enginerring has been top-down; we make things smaller and smaller. The bottom-up approach means taking your cue from biological processes (or nature) and encouraging objects to build themselves or to ‘grow’. There’s more here.

The Project for Emergining Nanotechnologies’ June 17, 2009 event (mentioned in yesterday’s posting) has been rescheduled to Fall 2009.


Fish camouflage, Australian webinar for nano business, medical nanobots in your bloodstream and Simon Fraser U has nano news

First off, the American Chemical Society (ACS) has declared ‘The Nano Song‘ a winner (in the People’s Choice and Critic’s Choice categories)  in their ACS Nanotation web community video contest ‘What is Nano?’.  If you haven’t seen the video yet, you can go here (scroll down).

Researchers at Sandia Labs are working to develop materials that change colour in the same that some fish can. Here’s how it works with the fish (from Nanowerk News here):

Certain fish species blend with their environment by changing color like chameleons. Their tiny motor proteins carry skin pigment crystals in their “tails” as they walk with their “feet” along the microtubule skeletons of cells to rearrange the animal’s color display.

The fish change colour as the environment around them changes. The researchers led by George Bachand are trying to enable synthetic or hybrid materials to do the same thing. Applications could be for military and/or fashion.

If you’re interested in the business end of nano, then there’s a webinar courtesy of the Australian Office of Nanotechnology coming up on April 29, 2009. NanoVentures Australia CEO, Peter Binks, will be talking about nanotechnology’s impact on global markets and industries.

Researchers at Pennsylvania State University (US) are honing in on a way to get hordes of microrobots (or nanobots) that have been introduced into the bloodstream to flock or swarm together so they can repair organs or deliver drugs to a specific target. I gather the problem has been  getting the machines to work together and the proposed solution is to use UV light. More details here.

Finally, some latebreaking news from Simon Fraser University (Vancouver, Canada). The university’s nano research facility, 4D Labs, has won funding (roughly $884, 000) from the federal government’s Western Economic Diversification agency to build a maskwritiing facility.  More about this tomorrow.
