"Fibered optical nano-tweezers"

Optical tweezers are nowadays a standard tool for non-invasive manipulation in biology, physical chemistry and soft condensed matter physics. Sophisticated commercial instruments, based on the original approach of strong laser beam focusing, are available. In parallel, optical fiber-based tweezers have been developed. They are less cumbersome and more versatile for trapping in complex systems.
The basics of optical trapping will be presented before giving a review of recent developments on fiber-based optical tweezers. Finally the results obtained at Institut Néel on micro- and nano-particle trapping using different types of nano-structures fiber tips will be presented.
