The nanocube acts as the SWCNT as both a tether and ultrathin wire to conduct electrical signals, explained Timothy Fisher, a Purdue University professor of mechanical engineering who has been involved in the development. "It might be part of a catheter to continuously monitor blood glucose for diabetics;' Portefiield said."And it might have many other applications, including basic scientifc research to study diseases and biological processes" "That's because the sensing portion of the system extends out pretty far from the rest of the device so that it can more easily come into contact with target molecules. "It doesn't have to wait for those target molecules to diffuse down all the way to the surface and can move into other regions within the range of the tether for enhanced sensing." The findings were detailed in a paper in the January issue of the American Chemical Society journal ACS Nano.The research was conducted at the Birck Nanotechnology Center and the Bindley Bioscience Center in Purdue's Discovery Park¡£ |
