Optical tweezers is a technology that uses a three-dimensional potential well formed by a highly convergent laser beam to capture, manipulate and control tiny particles  Compared with mechanical tweezers, optical tweezers use a non-mechanical contact mode to complete the clamping and manipulation of cells  It first captures and fixes the target cells in a non-contact mode, and then performs precise operations on the cells
Because the optical tweezers cause very little damage to the cells, in life science research, almost all single-cell operations use the optical tweezers to perform
Only the optical tweezers can be used for non-contact capture and fixation of target cells.
