Optical Tweezers
An optical tweezers apparatus uses a tightly focused laser to generate a trapping force that can capture and move small particles under a microscope. Because it can precisely and non-destructively manipulate objects such as individual cells and their internal components, the optical tweezers is extremely useful in biological physics research. In this experiment the student will use optical twee...

متن کاملTheory of Optical Tweezers
We derive a partial-wave (Mie) expansion of the axial force exerted on a transparent sphere by a laser beam focused through a high numerical aperture objective. The results hold throughout the range of interest for practical applications. The ray optics limit is shown to follow from the Mie expansion by size averaging. Numerical plots show large deviations from ray optics near the focal region ...
متن کاملLights, action: optical tweezers
Optical tweezers were ®rst realized 15 years ago by Arthur Ashkin and co-workers at the Bell Telephone Laboratories. Since that time there has been a steady stream of developments and applications , particularly in the biologica l ®eld. In the last 5 years the ̄ow of work using optical tweezers has increased signi®cantly, and it seems as if they are set to become a mainstream tool within biologi...
