    Abstract

    The spatial resolution of scanning near-field optical microscope (SNOM) is limited by the size of an aperture for the light transmission and ranges 50-100 nm, although 20 nm resolution is demonstrated. Further improvement of the resolution seems problematic for the classical SNOM configurations because the number of photons seeping through an aperture is rapidly decreasing with the decrease of the aperture size. A number of approaches to improve the resolution, such as molecular exciton-based SNOM, apertureless SNOM and SNOM using fluorescence resonant energy transfer (FRET) between a single fluorescence center of the tip and the sample studied are proposed.
