Chirality in optical trapping and optical binding [PDF]
, 2015 Optical trapping is a well-established technique that is increasingly used on biological substances and nanostructures. Chirality, the property of objects that differ from their mirror image, is also of significance in such fields, and a subject of much ...

Quantitative Modeling and Optimization of Magnetic Tweezers [PDF]
Biophysical Journal, 2009 Magnetic tweezers are a powerful tool to manipulate single DNA or RNA molecules and to study nucleic acid-protein interactions in real time. Here, we have modeled the magnetic fields of permanent magnets in magnetic tweezers and computed the forces exerted on superparamagnetic beads from first principles.

Direct observation of chaperone-modulated talin mechanics with single-molecule resolution
Communications Biology, 2022 Chakraborty et al. uses single-molecule magnetic tweezers to investigate the chaperone-modulated talin protein mechanics. The results showed that chaperones are involved in the regulation of talin folding/unfolding under mechanical force with some ...

Precision preparation of strings of trapped neutral atoms [PDF]
, 2006 We have recently demonstrated the creation of regular strings of neutral caesium atoms in a standing wave optical dipole trap using optical tweezers [Y. Miroshnychenko et al., Nature, in press (2006)].
