2001 DEC 23 - (NewsRx.com & NewsRx.net) -- Scientists at Northwestern University have created a nanoparticle with a new shape that could be a useful tool in the race to detect biological threats.
The nanoprism, which resembles a tiny Dorito, exhibits unusual optical properties that could be used to improve biodetectors, allowing them to test for a far greater number of biological warfare agents or diseases at one time.
The simple method used to produce triangular nanoprisms in large quantities, using commercially available silver nanospheres, soap and visible light, is reported in the November 30, 2001, issue of the journal Science.
