Plasmonic optical trapping combined with time-resolved fluorescence microscopy

Not Accessible

Your library or personal account may give you access

Abstract

Plasmonic devices can extend the field of optical trapping down to the nanoscale, reaching trapping potentials for single macromolecules [1, 2]. However, most setups rely on transmission measurements. While this offers a label-free read-out, the small signal change of transmission measurement with presence of particles limits the measurement accuracy.
