HIV, hepatitis, herpes, cancer detecting nanosensor

Dmitry Fedyanin and Yury Stebunov from the Moscow Institute of Physics and Technology have developed a highly sensitive  biological object detecting nanosensor.

The tiny sensor analyzes the chemical composition of substances and can detect viral disease markers in HIV, hepatitis, and herpes.  It can also help doctors identify tumor markers.

The optical sensor can track changes of  a few kilodaltons in the mass of a cantilever in real time.  The researchers believe that this can help diagnose diseases long before they can be detected by other methods.
