Here we propose the use of the organic semiconductor polyaniline (PANI) for the
preparation of spherical-shaped microparticles to serve as handles in optical tweezers (OT) …

We propose a Bessel beam optical tweezers setup that can stably trap superparamagnetic
beads. The trap stiffness measured is practically independent of the radius of the Bessel …

We repeat the derivation of the forces of a single-beam gradient laser trap on a dielectric
sphere in the ray optics regime as first reported by Ashkin; in this case, however, we …

The light-fueled microparticle oscillator, exemplifying sustained driving in a static light

Our investigation reveals a groundbreaking discovery of a negative inverse orbital Hall effect
(IOHE) in Ge thin films. We employed the innovative orbital pumping technique where spin …

We present a novel approach to determine the optical properties of materials in the

The physical origins of the transverse optical binding force and torque beyond the Rayleigh
approximation have not been clearly expressed to date. Here, we present analytical …

An optical trap, also known as an optical tweezer, is a scientific instrument that uses a highly
focused laser beam to trap and manipulate microscopic particles, such as cells or individual …
