DOI: 10.1002/smll.202107657

Abstract: Metallic chiral nanoparticles (CNPs) promisingly function as asymmetric catalysts but lack an important study in thermal stability of optical activity that stems from metastable chiral lattices. In this work, annealing is applied to silver (Ag)… read more here.

DOI: 10.1039/c7nr05464e

Abstract: Chiral gradient force allows a passive separation of an enantiomer since its direction is dependent on the handedness of its chiral entities. However, chiral polarisability is much weaker than electric polarisability. As a consequence, the… read more here.

DOI: 10.1039/c9nr09736h

Abstract: We put forward an enantioselective method for chiral nanoparticles using optical tweezers. We demonstrate that the optical trapping force in a typical, realistic optical tweezing setup with circularly-polarized trapping beams is sensitive to the chirality… read more here.

DOI: 10.1073/pnas.2310469121

Abstract: Significance The Achilles heel of the best available antiviral mRNA vaccines and biomolecular drugs includes the loss of their potency due to viral mutations and thermal exposure. Chiral L- or D-penicillamine-coated CuS nanoparticles (NPs) provide… read more here.

DOI: 10.1364/oe.448987

Abstract: We report selective trapping of chiral nanoparticles via vector Lissajous beams. Local optical chirality densities appear in these beams by properly choosing the values of two parameters (p,q) that determine the polarization vectors of light.… read more here.

DOI: 10.1364/ol.543604

Abstract: In this Letter, we have proposed an all-optical scheme for chiral particle separation with a microcylinder-pair system (MCPS) with a micrometer scale channel, applicable in microfluidic environments. By illuminating the MCPS with two counter-incident plane… read more here.
