MSH: A technique that uses LASERS to trap, image, and manipulate small objects (biomolecules, supramolecular assembles, DENDRIMERS) in three dimensional space. (From Glossary of Biotechnology and Nanobiotechnology Terms, 4th ed.),NCI: A method utilized for the non-mechanical manipulation of nanoparticles. Small transparent objects can be isolated or fixed using focused laser light. The optical trap is based on the concept of photon momentum transfer and has many applications.
