Soft matter exhibits a multitude of intrinsic physico-chemical attributes. Their mechanical
properties are crucial characteristics to define their performance. In this context, the rigidity of …

Light carries energy and momentum. It can therefore alter the motion of objects on the
atomic to astronomical scales. Being widely available, readily controllable, and broadly …

Heterogeneous nanoscale extracellular vesicles (EVs) are of significant interest for disease
detection, monitoring, and therapeutics. However, trapping these nano-sized EVs using …

This study addresses the challenge of trapping nanoscale biological particles using optical
tweezers without the photothermal heating effect and the limitation presented by the …

Here we functionalized micro-scaled polymer beads with nano-scaled quantum dots and
demonstrate optical trapping and tweezing, with in-situ fluorescence measurement, in an all …

The Belinfante spin momentum (BSM) is a fundamental yet enigmatic quantity of
electromagnetic fields. It vanishes from the global momentum of the field, but can be …

Optical and acoustic tweezers, despite operating on different physical principles, offer non-
contact manipulation of microscopic and mesoscopic objects, making them essential in …

In this paper, we present an approach called the free lens modulation (FLM) method to
generate high-perfection 3D generalized perfect optical vortices (GPOVs) with topological …

Double Nanohole Plasmonic Tweezers (DNH) have emerged as a powerful approach for
confining light to sub-wavelength volume, enabling the trapping of nanoscale particles much …

Among the long-standing efforts to elucidate the physical mechanisms of protein–ligand
catch bonding, particular attention has been directed at the family of selectin proteins …
