Abstract
The invention provides a nanoantenna scanning probe tip for microscropy or spectroscopy. The nanoantenna scanning probe tip includes a sharp probe tip covered with a contiguous film of predetermined sized and shaped plasmonic nanoparticles. A method for forming the nanoantenna scanning probe tip by trapping nanoparticles having a predetermined size and shape at a liquid surface using surface tension, forming a uniform and organized monolayer film on the liquid surface, and then transferring portions of the film to a sharp probe tip. In preferred embodiments, the sharp probe tip is one of a conductive STM (scanning tunneling microscopy) tip, a tuning fork tip or an AFM (atomic force microscopy) tip. The sharp tip can be blunted with an oxide layer.
