Optical tweezers: wideband microrheology [PDF]
Journal of Optics, 2010 Microrheology is a branch of rheology having the same principles as conventional bulk rheology, but working on micron length scales and micro-litre volumes.

Towards absolute calibration of optical tweezers [PDF]
Applied Physics Letters, 2006 Aiming at absolute force calibration of optical tweezers, following a critical review of proposed theoretical models, we present and test the results of MDSA (Mie-Debye-Spherical Aberration) theory, an extension of a previous (MD) model, taking account ...

Nanoscale virtual potentials using optical tweezers [PDF]
Applied Physics Letters, 2018 We combine optical tweezers with feedback to impose arbitrary potentials on a colloidal particle. The feedback trap detects a particle's position, calculates a force based on an imposed "virtual potential," and shifts the trap center to generate the ...

Optical Tweezers and Immunoassay [PDF]
Clinical Chemistry, 1997 Our scientific ancestors who advanced the atomic and molecular theories of matter and the cellular basis of biological organisms would be astounded by our current ability to visualize and manipulate atoms, molecules, and cells. The new techniques of atomic force microscopy (AFM; or scanning force microscopy) (1)(2)(3)(4) and optical trapping (optical ...

Comparing Femtosecond Optical Tweezers with Conventional CW Optical Tweezers [PDF]
arXivIn this work, we present a comparative study between continuous-wave (CW) and pulsed optical tweezers for 250 nm, 500 nm and 1-micron radius polystyrene beads at 5 different laser powers. We have used a Ti:Sapphire (MIRA 900F) laser that can be easily switched from CW to pulsed mode of operation, so there is no change in the experimental conditions in ...

Formation of Ultracold Molecules by Merging Optical Tweezers. [PDF]
Physical Review Letters, 2023 We demonstrate the formation of a single RbCs molecule during the merging of two optical tweezers, one containing a single Rb atom and the other a single Cs atom.

Optical tweezers in a dusty universe [PDF]
The European Physical Journal Plus, 2021 AbstractOptical tweezers are powerful tools based on focused laser beams. They are able to trap, manipulate, and investigate a wide range of microscopic and nanoscopic particles in different media, such as liquids, air, and vacuum. Key applications of this contactless technique have been developed in many fields. Despite this progress, optical trapping
