Over the past two decades, the development of plasmonic nanoparticle (NPs), especially
gold (Au) NPs, is being pursued more seriously in the medical fields such as imaging, drug …

Optical trapping and manipulation of micrometre-sized particles was first reported in 1970.
Since then, it has been successfully implemented in two size ranges: the subnanometre …

Optical tweezers are devices that use a single, strongly focused laser beam for the remote,
noncontact trapping and manipulation of microscopic objects. Since the first demonstration …

Single-molecule force spectroscopy has emerged as a powerful tool to investigate the forces
and motions associated with biological molecules and enzymatic activity. The most common …

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

Optical trapping is an established field for movement of micron-size objects and cells.
However, trapping of metal nanoparticles, nanowires, nanorods and molecules has received …

The possibility for the manipulation of many different samples using only the light from a
laser beam opened the way to a variety of experiments. The technique, known as Optical …

Highly efficient counter-propagating fiber-based optical traps are presented which utilize
converging beams from fibers with 3D printed diffractive Fresnel lenses on their facet. The …

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 …

Optical trapping is the craft of manipulating objects with light. Decades after its first inception
in 1970, the technique has become a powerful tool for ultracold‐atom physics and …
