Fluorescence Resonance Energy Transfer Microscopy — •Julia Tisler, Gopalakrishnan Balasubramanian, Rolf Reuter, Anke Lämmle, Fedor Jelezko, and Jörg Wrachtrup — 3. Physikalisches Institut, Stuttgart, Germany

We present fluorescence resonance energy transfer (FRET) between a single nitrogen-vacancy (NV) center in diamond and organic dye molecule.

A nanodiamond with a single NV colour center was placed to the tip of a atomic force microscope. Using this single NV center as a probe the sample was investigated. By scanning such tip over a sample containing dye molecules we were able to perform FRET microscopy. This new technique uses Förster energy transfer as optical contrast mechanism. Resolution of such scanning probe microscope is shown to be orders of magnitude better than that imposed by Abbe limit.
