Chirality in Optical Trapping and Optical Binding [PDF]
Photonics, 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 ...

Enhanced optical trapping [PDF]
Optical Manipulation and Structured Materials Conference 2020, 2020 Optical tweezers have contributed substantially to the advancement of micro-manipulation. However, they do have restrictions, mainly the limited range of materials that yield to optical trapping. Here we propose a method of employing optically trapped objects to manipulate the surrounding fluid and thus particles freely diffusing within it.

Review of Scientific Instruments, 2004 Since their invention just over 20 years ago, optical traps have emerged as a powerful tool with broad-reaching applications in biology and physics. Capabilities have evolved from simple manipulation to the application of calibrated forces on—and the measurement of nanometer-level displacements of—optically trapped objects.

Optical Trapping of Nanoparticles [PDF]
Journal of Visualized Experiments, 2013 Optical trapping is a technique for immobilizing and manipulating small objects in a gentle way using light, and it has been widely applied in trapping and manipulating small biological particles. Ashkin and co-workers first demonstrated optical tweezers using a single focused beam.

Optically programmable excitonic traps [PDF]
Scientific Reports, 2013 With atomic systems, optically programmed trapping potentials have led to remarkable progress in quantum optics and quantum information science. Programmable trapping potentials could have a similar impact on studies of semiconductor quasi-particles, particularly excitons.

Electro-Optical Ion Trap for Experiments with Atom-Ion Quantum Hybrid Systems
Applied Sciences, 2020 In the development of atomic, molecular, and optical (AMO) physics, atom-ion hybrid systems are characterized by the presence of a new tool in the experimental AMO toolbox: atom-ion interactions.

Practical axial optical trapping [PDF]
Review of Scientific Instruments, 2012 We describe a new method for calibrating optical trapping measurements in which tension is applied in the direction of the laser beam to a molecule tethered between a surface and an optically trapped bead. Specifically, we present a generally-applicable procedure for converting from the measured scattering intensity and the measured stage displacement ...
