(UCI 6/9/05) http://today.uci.edu/news/release_detail.asp?key=1337 MIT's Nanoprinter Could Mass-produce Nano-devices. Just as the printing press revolutionized the creation of reading matter, a "nano-printing" technique developed at MIT could enable the mass production of nano-devices currently built one at a time. The most immediate candidate for this innovation is the DNA microarray, a nano-device used to diagnose and understand genetic illnesses such as Alzheimer's, viral illnesses such as AIDS, and certain types of cancer. The ability to mass produce these complex devices would make DNA analysis as common and inexpensive as blood testing, and thus greatly accelerate efforts to discover the origins of disease.

The world's smallest brushes, with bristles more than a thousand times finer than a human hair, have been created by researchers in the US. The brushes can be used for sweeping up nano-dust, painting microstructures and even cleaning up pollutants in water. The bristles' secret is carbon nanotubes, tiny straw-like molecules just 30 billionths of a metre across. They are incredibly tough and yet flexible enough that they will yield when pushed from the side. The researchers behind the brushes were led from Rensselaer Polytechnic Institute in Troy, New York. Their work is reported in the journal Nature Materials. (BBC 6/12/05) http://news.bbc.co.uk/1/hi/sci/tech/4085214.stm 'Emerging Sectors' maps new type of summer camp.
