A handheld DNA detector may soon be a reality

Abstract:
A National University at San Diego researcher has taken a mathematical approach to a biological problem - how to design a portable DNA detector, which can help make life easier for environmental scientists testing contaminated sites.

In the research, Samuel Afuwape of the National University, in San Diego, California, 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.

Clinicians and medical researchers too could use it to diagnose genetic disorders and study problems in genetics.

Such a sensor might also be used to spot the weapons of the bioterrorist or in criminal forensic investigations.
