Biosensor to detect avian influenza virus

The Professor Zhou and Thompson of the University of Southern California have developed a prototype biosensor which could be useful in the fight against virus outbreaks.

A biosensor is a biological device to detect biochemical changes in the body and transmitted to a device capable of interpreting them. Since 2001, the biosensors "nanowires," tiny, have shown their effectiveness in detecting proteins.

The prototype made by Professor Zhou and Thompson is able to detect the N protein of the H5N1 virus. The nano biosensor detects molecules quickly, without the use of chemical agents, and for a lower cost compared to other techniques used to detect the SARS virus.

Researchers are now testing the prototype in the blood by adding chips and filters. Its application could be extended to other fields of research.
