Optical microcavities: Label-free detection down to single virus particles

Frank Vollmer, Stephen Arnold

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Binding of Influenza A virus particles is detected from the frequency shift of a microsphere cavity. To overcome limitations posed by diffusion, transport of nanoparticles to the sensing region is enhanced by optical gradient forces.
