MeSH Heading: Microscopy, Scanning Tunneling
Tree Number(s): E01.370.350.515.666.500; E05.595.666.500
Unique ID: D016252
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D016252
Scope Note: A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.
