Abstract

The emergence of nanowire devices as a powerful and general class of ultrasensitive electrical sensors for the direct detection of biological and chemical species, is discussed. Nanosensors can be used for the detection of proteins, DNA, drug molecules and viruses upto single molecules. Nanowire field-effect sensor devices with specific surface receptors can be used for the broad range detection of biological and chemical species in solution. The simplicity, single viral particle detectivity and the capability of the nanowire sensors in selective multiplexed detection, suggests its usage as a powerful viral-sensing devices for medical and bioterrorism applications.
