Development of electromagnetic tweezers for single-molecule energetics of kinesin

Biophysics and Physicobiology
Optical tweezers have enabled single-molecule measurements of kinesin mechanics and energetics but face challenges for in vivo applications due to photothermal effects and refractive-index-dependent force calibration.

Optical Tweezers to Study Viruses

, 2013
A virus is a complex molecular machine that propagates by channeling its genetic information from cell to cell. Unlike macroscopic engines, it operates in a nanoscopic world under continuous thermal agitation. Viruses have developed efficient passive and active strategies to pack and release nucleic acids.

Comparing Femtosecond Optical Tweezers with Conventional CW Optical Tweezers

In 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 ...
