This document presents information about nanotribology. It begins with an introduction and definitions of tribology and nanotribology. It then discusses the scientific background of friction at the nanoscale, including empirical laws of friction. The document outlines three main tools used in nanotribological studies: surface force apparatus, scanning tunneling microscope, and atomic force microscope. Applications of nanotribology are mentioned, including in MEMS/NEMS and energy storage. In the conclusion, the importance of nanotribological measurement for high performance machinery is emphasized. References on the topic are listed at the end.

and "logy". "Tribo" means rubbing and "logy" means
knowledge..

11.  In order to achieve high performance in any
lubricated body, assembly of mechanical
part, it is very essential to study surface
adhesion, surface wear and behavior of
materials at nano level and this would be
possible only by Nanotribological
measurement tool.
