10000 times volume reduction for fluorescence correlation spectroscopy using nano-antennas
We present an experimental and theoretical study of a new scheme for Near-Field Fluorescence Correlation Spectroscopy that, using the field enhancement by optical nanoantennas, allows the reduction of the observation volume 4 orders of magnitude below the diffraction limit. This reduction can be use...
