Optically enhanced acoustophoresis [PDF]
Optical Trapping and Optical Micromanipulation XIV, 2017 Regenerative medicine has the capability to revolutionise many aspects of medical care, but for it to make the step from small scale autologous treatments to larger scale allogeneic approaches, robust and scalable label free cell sorting technologies are needed as part of a cell therapy bioprocessing pipeline.

Optically enhanced electron attachment [PDF]
Physical Review Letters, 1987 The first optically enhanced electron attachment involving electronically excited molecules is reported. The metastable (triplet) states responsible for the photoenhanced electron attachment were produced indirectly via internal conversion from higher excited singlet states which are strongly optically allowed and are reached by excimer-laser ...

Quantum-Enhanced Optical-Phase Tracking [PDF]
Science, 2012 Keeping Track of Photon Phase In optical interferometers or optical communications, information is often stored in terms of the phase of the waveform or light pulse. However, fluctuations and noise can give rise to random jitter in the phase and amplitude of the optical pulses, making it difficult to keep track of the phase.

Local versus bulk circular dichroism enhancement by achiral all-dielectric nanoresonators
Nanophotonics, 2022 Large optical chirality in the vicinity of achiral high-index dielectric nanostructures has been recently demonstrated as useful means of enhancing molecular circular dichroism.

Controlling molecular broadband-emission by optical confinement [PDF]
, 2008 We investigate experimentally and theoretically the fluorescence emitted by molecular ensembles as well as spatially isolated, single molecules of an organic dye immobilized in a quasi-planar optical microresonator at room temperature.
