Optical Tweezers - An Introduction to Optical Tweezers

WebApr 12, 2024 · In a fiber-based optical tweezer system, it is a common practice to insert the fiber probe into the sample solution to perform the tweezer function. Such a configuration of the fiber probe may lead to unwanted contamination and/or damage to the sample system and is thus potentially invasive. Here, we propose a completely non-invasive method for … WebOptical tweezers produce a restoring force to hold the micrometer-sized plastic microsphere at the focus. This restoring force is linearly related to displacement (i.e., it is Hookean) over a distance of about ±250 nm. The bead position can therefore be used to measure both force and movement.
