In the first part of the seventeenth century, the German astronomer Johannes Kepler
proposed that the reason comet tails point away from the sun is because they are pushed in …

Functional particles are prepared directly by heterogeneous polymerization, eg emulsion
polymerization and dispersion polymerization. Modification of existing particles is another …

Scattering forces in focused light beams push away metallic particles. Thus, trap**
metallic particles with conventional optical tweezers, especially those of Mie particle size, is …

We demonstrate three-dimensional trap** of low-index particles (20-μ m-diameter hollow
glass spheres in water) by using a single, strongly focused, stationary dark optical vortex …

Metallic objects reflect light and have generally been considered poor candidates for optical
traps, particularly with optical tweezers, which rely on a gradient force to provide trap** …

Optical tweezers were first realized 15 years ago by Arthur Ashkin and co-workers at the Bell
Telephone Laboratories. Since that time there has been a steady stream of developments …

We review the combinations of optical micro‐manipulation with other techniques and their
classical and emerging applications to non‐contact optical separation and sorting of micro …

This Perspective describes recent progress in optical trap**s of nanoparticles based on
localized surface plasmon. This plasmonic optical trap** has great advantages over the …

Microfluidic technology has emerged as a promising tool in various applications, including
biosensing, disease diagnosis, and environmental monitoring. One of the notable features of …

The controlled manipulation of matter using radiation pressure, otherwise known as optical
trap**, has emerged as a powerful experimental tool in the physical sciences. One …
