Optical angular-momentum transfer to trapped absorbing particles
Marlies Friese,Marlies Friese,Jonas Enger,Jonas Enger,Halina Rubinsztein-Dunlop,Halina Rubinsztein-Dunlop,Norman R. Heckenberg,Norman R. Heckenberg +7 more
TL;DR: Bringing together 44 landmark papers, "Optical Angular Momentum" offers the first comprehensive overview of the subject as it has developed and gives a definitive statement of the current status of all aspects of optical angular momentum.
Optical Spectroscopy of Single Trapped Metal Nanoparticles in Solution
Juris Prikulis,Fredrik Svedberg,Mikael Käll,Jonas Enger,Kerstin Ramser,Mattias Goksör,Dag Hanstorp +6 more
TL;DR: In this paper, a simple method for the optical manipulation and spectroscopy of colloidal silver nanoparticles in aqueous solution using optical tweezers combined with dark-field microscopy is presented.

A microfluidic system enabling Raman measurements of the oxygenation cycle in single optically trapped red blood cells
TL;DR: The possibility of selecting a single cell with certain properties and following its dynamics after an environmental stimulation in real time using Raman spectroscopy is demonstrated using a micro Raman set-up with optical tweezers and a microfluidic system.

Resonance Raman spectroscopy of optically trapped functional erythrocytes
TL;DR: A novel setup combining a micro-Raman spectrometer with external optical tweezers suitable for resonance Raman studies of single functional trapped cells is introduced, finding that great care has to be taken in order to avoid photodamage caused by the visible Raman excitation, whereas the IR trapping irradiation does not seem to harm the cells or alter the hemoglobin Raman spectra.

Optical manipulation and microfluidics for studies of single cell dynamics
Emma Eriksson,Jan Scrimgeour,Annette Granéli,Kerstin Ramser,Rikard Wellander,Jonas Enger,Dag Hanstorp,Mattias Goksör +7 more
TL;DR: In this paper, the authors show how optical manipulation, imaging and microfluidics can be combined for investigations of single cells, in combination with optical tweezers, to enable environmental changes for single cells.
