Research output: Contribution to conferencePaperpeer-review

Abstract

Fluorescence imaging of single molecules was conducted using a super resolution near-field scanning optical microscopy (NSOM). The incident light was reduced using neutral density filters to avoid photobleaching of single molecules during the fluorescence imaging. The results show that the 15 nm spatial resolution is obtained which is smaller than the aperture diameter and is attributed to nonradiative energy transfer from the excited molecules to the coated metal of the probe.
