LABEL FREE DETECTION OF VIRUS-LIKE PARTICLES

摘要

The detection and quantification of aqueous suspensions of virus particles is critical for a wide variety of applications, ranging from medical diagnostics, homeland security, food and drug production, to water sanitation. Advances in virus detection technologies are expected to yield significant savings in cost and time. Here we present the use of a label free evanescent optical field based biosensor for the sensitive detection of nanoparticles with physical and optical properties similar to those of many viruses.
