A robust protocol for nanoscale chemical imaging using tip-enhanced Raman spectroscopy (TERS) has been developed.

A real-time hyperspectral imaging technique can identify dirt and bacteria on surfaces leading to informed decisions as to when and how much to clean.

The bleaching of corals is an indication of their poor health due to the stress of increased water temperature and other factors. A cost-effective solution to monitor coral health, based on a fluorescence hyperspectral camera mounted on an underwater remotely operated vehicle (ROV), is being developed by scientists at the University of Bristol, UK, and Sealife London Aquarium.

A new miniature broadband IR emitter enables spectroscopy and hyperspectral imaging miniaturisation.
