Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

Propulsive effects of light, which often remain unnoticed in our daily-life experience, manifest
themselves on spatial scales ranging from subatomic to astronomical. Light-mediated forces …

We propose a method for peristaltic transport of nanoparticles using the optical force field
over a nanostructured surface. Nanostructures may be designed to produce strong near …

We present a system employing a dynamic diffractive optical element to control properties of
two counter-propagating beams overlap** within a sample chamber. This system allows …

Optical evanescent wave in total internal reflection has been widely used in efficient optical
manipulation, where the object is trapped by the intrinsic intensity gradient of the evanescent …

We examine the rotational dynamics of spheroidal particles in an optical trap comprising
counter-propagating Gaussian beams of opposing helicity. Isolated spheroids undergo …

We present a theoretical investigation of the stochastic dynamics of a damped particle in a
tilted periodic potential with a double well per period. By applying the matrix continued …

We present theoretical results related to the optical binding of two nanoparticles (NPs) in a
standing wave created by a retro-reflected wide Gaussian beam. Recent experimental …

Near-field patterns of light provide a way to optically trap, deliver, and sort single nanoscopic
particles in a wide variety of applications in nanophotonics, microbiology, and …

We report size-dependent trap** and delivery of polystyrene submicro-spheres using a
600 nm diameter fibre. Theoretical results show that both gradient and scattering forces …
