Chemists in South Korea have created a stable color-changing sensor that displays an easily quantifiable response to the pH of its surroundings. Published in Microsystems & Nanoengineering, Dong-Hwan ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At ...

Maintaining pH within a particular range is crucial for cell survival. Although some organisms can survive and even prosper in a wider pH range than others, bioprocessing’s popular Chinese hamster ...

Researchers developed a novel nanopigment for colorimetric pH sensing, ensuring linear accuracy from pH 1 to 10 with enhanced stability and no leaching.

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...
