Optical tweezers are standard today. Recently, more sophisticated trapping configurations have been realized based on holographic beam shaping techniques.
Blue laser diodes operated in stimulated emission offer a potential alternative to traditional solid-state lighting based on light-emitting diodes.
A new compact sensor system based on an LED pumped polymer laser detects explosive vapors quickly and sensitively.
Mapping of chemical contents and their spatial distribution in a complex biological environment such as cells can be achieved by a new imaging modality.
A new tool enables biomechanical studies of individual cells, laser-propelling red blood cells over long distances and monitoring their deformation.
Raman spectroscopy provides molecular specificity through spectrally-resolved measurement of the inelastic scattering under monochromatic excitation.
