There must be no chemical reaction between the sensor material and the sample. Use a sensor with a low cell constant (0.01 to 0.1 cm-1) for low conductivity measurements and a sensor with a higher ...

Researchers at the Indian Institute of Science (IISc) have developed a unique luminescent probe that uses terbium, a rare earth metal, to sense the presence of an enzyme called β-glucuronidase, which ...
