Optical tweezers are a technology that uses a three-dimensional potential well formed by a highly converging laser beam to capture, manipulate, and control tiny particles. Compared to mechanical tweezers, optical tweezers use non-mechanical contact to hold and manipulate cells. , It first performs non-contact capture and fixation of target cells, and then performs precise operations on the cells. Because optical tweezers cause very little damage to cells, in life science research, almost all single-cell operations use light Use forceps to control. Can be inferred from this. ['All methods for precise manipulation of cells have minimal damage to the cells.', 'Non-contact capture and fixation of target cells can only use optical tweezers.', 'Almost all non-single-cell operations are not controlled by optical tweezers.', 'Everything that uses mechanical contact to hold and manipulate cells is not optical tweezers.']
