Nanoscopy

Part of speech: noun

Definitions

1. The use of advanced imaging techniques to observe structures and objects at the nanometer scale, far below what an ordinary light microscope can resolve
2. A branch of imaging that examines matter at dimensions measured in billionths of a metre, using specialized instruments such as electron or probe microscopes
3. Visualization of extremely small features, on the order of nanometres, made possible by high-resolution techniques beyond conventional optical magnification

Etymology: "Nanoscopy" is a modern compound built from two Greek-derived elements. The first, "nano-", comes from the Greek "nanos", meaning "dwarf", and in modern science it denotes a factor of one billionth, so a nanometre is one billionth of a metre. The second, "-scopy", comes from the Greek "skopein", "to look at" or "to examine", the same root that gives "microscope" and "telescope". Put together, the word names the act of seeing structures at the scale of nanometres, which lies far below what an ordinary light microscope can resolve. Because it is a deliberate combination of established scientific prefixes rather than a word with a long folk history, its meaning follows directly from its parts: "nano-" sets the scale and "-scopy" sets the activity of observing.
