Sensors for pH, ORP, and temperature are immersed in pool water flowing through a bypass pipe that runs between the filter and the pump.

Chemists develop new sensor for microvolume pH detection by Xi'an jiaotong-Liverpool University A The schematic drawing of the as-prepared microfluidic solid-state pH sensor.

New cryo electron microscopy structures of bluetongue virus (BTV) under low- and high-pH conditions reveal pH sensors that mediate host-membrane fusion and penetration by a nonenveloped virus.

The sensor, which L’Oreal with microfluidics company Epicore Biosystems, uses trace amounts of sweat to determine where your pH levels are on a scale of 1 to 14.

Last year, L’Oreal brought a nifty little UV sensor to CES. The idea was it was supposed to help you monitor your UV exposure and tailor a skin care regimen based on environmental factors. And ...

A bioresorbable, cordless, passive sensor that monitors pH locally and detects stomach leakage early on.
