become an essential tool in several fields of physics, spectroscopy, biology …

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

Chirality arises universally across many different fields. Recent advancements in artificial
nanomaterials have demonstrated chiroptical responses that far exceed those found in …

Demonstration of the light radiation pressure on a microscopic level by A. Ashkin led to the
invention of optical tweezers (OT). Applied in the studies of living systems, OT have become …

The discipline of biophotonics or biomedical optics has undergone a fascinating journey in
