Optical gradient force on chiral particles
WebThe gradient force is the significant part in single beam optical trapping procedure, because it is oriented perpendicular to the axis and push particles towards a region with higher optical intensity. Thus, the gradient force ensures … WebSep 22, 2024 · By optically trapping the chiral gold nanoparticles, the study team observed the optical gradient force arising from the chirality (i.e., the difference between the gradient force by left- and right-circularly polarized light). The results indicated that the optical gradient force was distinct for particles in the D- and L-forms.
