With its momentum transfer, light is a primary tool for manipulating microscale objects in
various research fields, including physics, chemistry, and biology. Optical force fields, also …

A methodology to manipulate bubbles and measure adhesion forces is presented and
validated. Holographic optical tweezers are employed to establish a circular array of high …

If a colloidal particle is exposed to an external field, its Brownian motion is modified. In the
case of an anisotropic particle, the external potential might not only affect its translation but …

Spatially modulated optical fields provide the perspective of tuning nanoparticle (NP)
dynamics in a colloidal suspension. Here, it is shown that the lateral interferometric optical …

We use molecular dynamics simulations to investigate the ordering phenomena in two-
dimensional (2D) liquid crystals over the one-dimensional periodic substrate (1DPS). We …

Using a ray tracing calculation, the energy landscape of dumbbells, made of spherical
colloidal particles, interacting with a periodic distribution of light is calculated. As shown …

Near vertical optically trapped dimers, composed of pairs of microspheres, and constructed
in situ, were imaged in bright-field in flow and at rest, and with displacement Δz from the …
