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

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 …

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 force exerted by an optical trap on a dielectric bead in a fluid is often found by fitting a
Lorentzian to the power spectrum of Brownian motion of the bead in the trap. We present …

To probe the dynamics and size of lipid rafts in the membrane of living cells, the local
diffusion of single membrane proteins was measured. A laser trap was used to confine the …

Nanotechnology, science, and engineering spearhead the 21st century revolution that is
leading to fundamental breakthroughs in the way materials, devices, and systems are …

One crucial challenge for subwavelength optics has been the development of a tunable
source of coherent laser radiation for use in the physical, information and biological …

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 …

We explain and demonstrate a new method of force and position calibrations for optical
tweezers with back-focal-plane photodetection. The method combines power spectral …

As nanometer-scale portals in biological membranes, protein ionic channels act as
gatekeepers, controlling the traffic of ions and macromolecules into and out of cells …
