Force measurements with optical tweezers inside living cells [PDF]
, 2014 The force exerted by optical tweezers can be measured by tracking the momentum changes of the trapping beam, a method which is more general and powerful than traditional calibration techniques as it is based on first principles, but which has not been ...

Controllable asymmetrical potential wells created by phase profiles of light
Results in Physics, 2021 Optical tweezers, which exploit laser beams to control various particles, have been widely used in many fields. However, the potential wells are typically symmetrical in optical traps, which limit the performance of manipulating particles.

Composite Diffraction-Free Beam Formation Based on Iteratively Calculated Primitives
Micromachines, 2023 To form a diffraction-free beam with a complex structure, we propose to use a set of primitives calculated iteratively for the ring spatial spectrum. We also optimized the complex transmission function of the diffractive optical elements (DOEs), which ...

Compliant rolling-contact architected materials for shape reconfigurability
Nature Communications, 2018 The authors introduce a compliant rolling-contact architected material as a class of shape reconfigurable mechanical metamaterial. They also devise an approach that combines two photon stereolithography and scanning holographic optical tweezers, which ...

Microrheology with optical tweezers: data analysis [PDF]
, 2012 We present a data analysis procedure that provides the solution to a long-standing issue in microrheology studies, i.e. the evaluation of the fluids' linear viscoelastic properties from the analysis of a finite set of experimental data, describing (for ...
