Microscopy: Optical Traps: An Introduction (Carlos Bustamante)

Learn more: https://www.ibiology.org/talks/optica... Light can exert force on physical objects. In optical trapping this is used to immobilize objects (often beads) in a focussed laser beam. These videos describe the principles of optical traps, show how to build and calibrate optical traps and show how optical traps are used in the study of molecular motors.
