Optical sorting of small chiral particles by tightly focused vector beams

Optomechanical Wagon‐Wheel Effects for Bidirectional Sorting of Dielectric Nanoparticles

“…The movements can be DOI: 10.1002/lpor.202000546 poles apart even in the lateral direction, via the interaction of light with particles of opposite chiralities. [16][17][18][19][20][21][22][23] These intriguing phenomena enrich optomechanics and offer a two-way selection scheme for all-optical particle sorting.…”

Optical separation and discrimination of chiral particles by vector beams with orbital angular momentum

“…In recent years, optical forces on chiral objects have attracted considerable attention not only for the optical separation of enantiomers but also for the further identification of chirality. [23][24][25][26][27][28][29][30][31][32] However, most of these studies have been restricted to the dipolar or geometric optics regime, [23][24][25][26][27][28][29][30] and use scalar beams with spatially uniform states of polarization (SOP) as illumination. [23][24][25][26][27][28][29]31,32 Moreover, it is usually need to change the SOP of incident beam to realize the recognition of another enantiomer.…”

Beam Shaping by a Magnetic Fluid Deformable Mirror With Curved Trajectory for Optical Tweezer System

“…Optical tweezers have found a wide range of applications in biophotonics and biomedicine, including the manipulation of biological cells [2] [3], force measurements in general [4], and the investigation of molecular motor properties [5]. Other important applications of optical tweezers can be found in colloidal sciences [6], microfluidics [7], or particle sorting [8]. Moreover, optical tweezers can be used to address fundamental physical questions concerning light-matter interaction [9] or hydrodynamic forces [10].…”
