Abstract
Fluorescence resonance energy transfer (FRET) has been observed between donor dye molecules deposited onto the sample surface and acceptor dye molecules deposited onto the scanning near-field optical microscope (SNOM) or atomic force microscope tip. FRET was observed only when the tip acquired a contact with the sample and took place in a region of few tens of square nanometers in size when thousands (hundreds) of molecules are involved. In view of the obtained results, the perspectives for the construction of a one-atom FRET SNOM are described.
