<? pag\vskip-16pt?> Harnessing linear and angular momenta of light is one of the
cornerstones in modern optics and has found tremendous applications in optical circuits …

The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

Optical tweezers are tools made of light that enable contactless pushing, trapping, and
manipulation of objects, ranging from atoms to space light sails. Since the pioneering work …

Colloidal particles of controlled size are promising building blocks for the self-assembly of
functional materials. Here, we systematically study a method to synthesize monodisperse …

We review the experimental synthesis of smooth and rough particles, characterization of
surface roughness, quantification of the pairwise and bulk friction coefficients, and their …

Optical trapping and manipulating nanoparticles are essential tools for interrogating
biomedicine at the limits of space and time. Typically, silica or polystyrene microspheres are …

We introduce herein an efficient microfluidic approach for continuous transport and localized
collection of nanoparticles via hybrid electrokinetics, which delicately combines linear and …

Mobile microrobots have the potential to transform medical treatments based on therapeutic
delivery. Specifically, microrobots are promising candidates for cell transportation in cell …

Organosilica nanoparticles refer to silica nanoparticles containing carbon along with organic
or functional groups and can be divided into mesoporous organosilica nanoparticles and …

Increasing significance is being placed on the synthesis of smart colloidal particles, since
the route to various meta-materials has been outlined through their bottom-up self-assembly …
