Columbia Engineering and Penn researchers increase speed of single-molecule measurementsNew York NY (SPX) Mar 21, 2012 As nanotechnology becomes ever more ubiquitous, researchers are using it to make medical diagnostics smaller, faster, and cheaper, in order to better diagnose diseases, learn more about inherited traits, and more. But as sensors get smaller, measuring them becomes more difficult-there is always a tradeoff between how long any measurement takes to make and how precise it is. And when a signal is very weak, the tradeoff is especially big. A team of researchers at Columbia Engineering, led by Electri ... read more |
