Particle-based nanosensors offer a tool for determining the pH in the endosomal-lysosomal system of living cells. Measurements providing absolute values of pH have so far been restricted by the ...

Chloride and protons perform important closely related roles in many cellular responses. Here we developed a ratiometric biosensor, ClopHensor, based on a highly chloride-sensitive Aequorea victoria ...

A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...
