'Volumetric' imaging method reveals chemical content

A "chemical imaging" system that uses a special type of laser beam to penetrate deep into tissue might lead to technologies that eliminate the need to draw blood for analyses including drug testing and early detection of ...

Chip-based nanoscopy: Microscopy in HD quality

Physicists at Bielefeld University and the Arctic University of Norway in Tromsø have developed a photonic chip that makes it possible to carry out super-resolution light microscopy, also called 'nanoscopy,' with conventional ...
