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

The pace of innovations in the field of optical trapping has ramped up in the past couple of
years. The implementation of structured light, leading to groundbreaking inventions such as …

The fastest-spinning man-made object is a tiny dumbbell rotating at 5 GHz. The smallest
wind-up motor is constructed from a DNA molecule. Picoliter volumes of fluids are remotely …

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 ever‐growing field of microfluidics requires precise and flexible control over fluid flows
at reduced scales. Current constraints demand a variety of controllable components to carry …

Active particles break out of thermodynamic equilibrium thanks to their directed motion,
which leads to complex and interesting behaviors in the presence of confining potentials …

Thermally activated transitions are ubiquitous in nature, occurring in complex environments
which are typically conceived as ideal viscous fluids. We report the first direct observations …

Since Allen et al recognized that light beams possessing a helical phase structure can carry
orbital angular momentum (OAM), OAM of light has witnessed groundbreaking …

It is shown in this work that, with strong focusing of a beam with optical vortex and circular
polarization, three energy flows take place in the focal plane: direct longitudinal, reverse …

Nitrogen-vacancy (NV) centers in diamond have emerged as promising room-temperature
quantum sensors for probing condensed matter phenomena ranging from spin liquids, two …
