The merging of the molecular specificity of Raman spectroscopy with the extraordinary optical properties of metallic nanoarchitectures is at the heart of Surface Enhanced Raman Spectroscopy (SERS), ...

Like swimming pools, hot tubs need regular monitoring to ensure their water stays clean and clear. An average person might take a water quality reading once or twice a week using test strips, but such ...

Many human metabolic functions only run smoothly if the acid level in the body remains neutral and stable. For humans, normal blood pH values lie between 7.35 and 7.45. By way of comparison, an empty ...

(Nanowerk News) Measuring the pH of substances gives us vital clues about the world around us, such as identifying contaminated water or checking the toxicity of medical or cosmetic products. Often, ...

For decades, the food and beverage industry’s been looking for a food safe, in-line pH sensor that withstands cleaning processes and doesn't have to be taken outside of the process. A new option ...

The Fraunhofer Institute for Photonic Microsystems IPMS has achieved another milestone in chemical liquid analysis. The electronics needed to control the ISFET have been successfully miniaturised. At ...
