WebDec 18, 2024 · the transverse gradient force and simultaneously accelerated along a curved trajectory via the longitudinal optical force. In particular, the longitudinal optical force can be remarkably enhanced by the particle chirality when the chirality is suffi-ciently large, while the transverse gradient force is nearly independent of the particle chirality. WebJul 21, 2024 · Using the optical gradient forces, conventional optical tweezers (OT) relying on highly focused laser beams are the most commonly used approach to trap and manipulate sub−micrometer particles in various studies, such as the physical [13,14,15] and biomechanical [16,17] research. However, conventional OTs are based on an objective … cycloplegics and mydriatics
