Optical trap** describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trap** with a single beam, this is …

Optical tweezers have become the method of choice in single-molecule manipulation
studies. In this Primer, we first review the physical principles of optical tweezers and the …

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 …

In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the
subject of intense research efforts. Plasmon physics is intriguing and its precise modelling …

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

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 …

Our understanding of the fate and distribution of micro-and nano-plastics in the marine
environment is limited by the intrinsic difficulties of the techniques currently used for the …

Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

Optical tweezers, tools based on strongly focused light, enable optical trap**,
manipulation, and characterisation of a wide range of microscopic and nanoscopic …

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