Handheld DNA detector

A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector. Writing in the International Journal of Nanotechnology, he describes a mathematical simulation to show how a new type of nanoscale transistor might be coupled to a DNA sensor system to produce a characteristic signal for specific DNA fragments in a sample.
