Quantum limited particle sensing in optical tweezers [PDF]
, 2009 Particle sensing in optical tweezers systems provides information on the position, velocity and force of the specimen particles. The conventional quadrant detection scheme is applied ubiquitously in optical tweezers experiments to quantify these ...

Ray Optics Model for Optical Trapping of Biconcave Red Blood Cells
Micromachines, 2022 Red blood cells (RBCs) or erythrocytes are essential for oxygenating the peripherical tissue in the human body. Impairment of their physical properties may lead to severe diseases. Optical tweezers have in experiments been shown to be a powerful tool for

Linear microrheology with optical tweezers of living cells 'is not an option'! [PDF]
, 2015 Optical tweezers have been successfully adopted as exceptionally sensitive transducers for microrheology studies of complex fluids. Despite the general trend, in this article I explain why a similar approach should not be adopted for microrheology ...

Acousto-holographic optical tweezers
Optics Letters, 2020 Acousto-optic deflectors (AODs) allow the creation of multiple optical traps by time-sharing, that is, by rapidly cycling the laser focus between designated spatial locations. The traps thus formed are not permanent. In this Letter, we successfully demonstrate the creation of multiple and permanent traps by means of AODs driven by specially encoded ...

On chip shapeable optical tweezers [PDF]
Scientific Reports, 2013 Particles manipulation with optical forces is known as optical tweezing. While tweezing in free space with laser beams was established in the 1980s, integrating the optical tweezers on a chip is a challenging task. Recent experiments with plasmonic nanoantennas, microring resonators, and photonic crystal nanocavities have demonstrated optical trapping.

Visual guide to optical tweezers [PDF]
European Journal of Physics 38(3), 034009 (2017), 2017 It is common to introduce optical tweezers using either geometric optics for large particles or the Rayleigh approximation for very small particles. These approaches are successful at conveying the key ideas behind optical tweezers in their respective regimes.

Accounting for polarization in the calibration of a donut beam axial optical tweezers. [PDF]
PLoS ONE, 2018 Advances in light shaping techniques are leading to new tools for optical trapping and micromanipulation. For example, optical tweezers made from Laguerre-Gaussian or donut beams display an increased axial trap strength and can impart angular momentum to

Optical measurement of torque exerted on an elongated object by a non-circular laser beam [PDF]
, 2004 We have developed a scheme to measure the optical torque, exerted by a laser beam on a phase object, by measuring the orbital angular momentum of the transmitted beam.
