Near-field scanning optical microscopy (NSOM) is a relatively new technique that combines ultra high optical resolution, down to 70 nm, with single molecule detection sensitivity. As such, the technique holds great potential for direct visualisation of domains at the cell surface. Yet, NSOM operation under liquid conditions is far from trivial.SNOM proper The systematic exploration of optical near fields for microscopy began in the early 1980s at the IBM Zurich Research Laboratory (Pohl, 1982) and, independently, at Cornell University (Lewis et al, 1983).
