Optical trapping has proven to be an efficient method to control particles, including biological
cells, single biological macromolecules, colloidal microparticles, and nanoparticles. Multiple …

We experimentally demonstrate the emergence of directional rotation in thermally active-
passive colloidal structures under optical confinement. The observed handedness of the …

Light carries momentum and, upon interaction with material structures, can exert forces on
them. Here, we show that a planar structure with asymmetric optical response is …

Controlled trapping of light-absorbing nanoparticles with low-power optical tweezers is
crucial for remote manipulation of small objects. This study takes advantage of the …

Angular optical trapping based on Janus microspheres has been proven to be a novel
method to achieve controllable rotation. In contrast to natural birefringent crystals, Janus …

Optical tweezers are precise tools for translating and rotating micrometer-sized particles and
are used widely in biology and physics. In a linearly polarized optical trap, Janus particles …

Harnessing localized heating through efficient light absorption has opened up exciting
possibilities for precise control of nanoscale systems. Such optothermal effects alter the …

From the earliest observations of deflection of comet tails by sunlight in the 17th century to
the sophisticated manipulation of microscopic entities using lasers in the 21st century, the …
