We describe a toolbox, implemented in Matlab, for the computational modelling of optical
tweezers. The toolbox is designed for the calculation of optical forces and torques, and can …

We review the use of the T-matrix description of scattering, or the T-matrix method, for the
calculation of optical forces and torques, especially for the computational modelling of …

Optical tweezers have found widespread application in many fields, from physics to biology.
Here, we explain in detail how optical forces and torques can be described within the …

It has been suggested that radially polarized beams can be used to improve the
performance of optical tweezers, with reduced scattering force resulting from both the …

We report an experimental study concerning the radial forces of an optical tweezers acting
on spherical polystyrene particles diluted in water solution. The radius of the trapped beads …

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 …

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

Since their development in the 1980s, optical tweezers have become a widely used and
versatile tool in many fields. Outstanding applications include the quantitative measurement …

We report a new mechanism for trapping metallic particles in inverted optical tweezers. The
particles are loosely confined, in three dimensions, to an annular region just below the beam …

We calculate trapping forces, trap stiffness and interference effects for spherical particles in
optical tweezers using electromagnetic theory. We show the dependence of these on …
