Hematite particles, which exhibit a high magnetic moment, are used to apply large forces on
physical and biological systems under magnetic fields to investigate various phenomena …

Particles can be assembled at the air-water interface due to optically induced local heating.
This induces convection currents in the water which brings particles to the surface. We …

The resonance between an electronic transition of a micro/nanoscale object and an incident
photon flux can modify the radiation force exerted on that object, especially at an interface. It …

Laser trapping at an interface provides a unique platform for assembling novel multiparticle-
based optical matter that extends well beyond the irradiated area. Optical binding, resulting …

Light can be guided without diffraction in prefabricated structures: optical fibers and
waveguides or in actively created spatial solitons in optically nonlinear media. Here, an …

Colloidal particles trapped by a focused laser at the air-liquid interface provide an interesting
assembly dynamic. In this study, we demonstrated manipulating optical force-induced …
