Measurement of pH values in human tissues by two-photon microscopy.


pH values go live! A ratiometric two-photon (TP) probe (NP1, see scheme) that has a significant TP action cross-section, high photostability, negligible toxicity, and can estimate pH values in live cells and human tissues by two-photon microscopy is described. NP1 can detect the difference in pH between live cells from the gastroesophageal junction (GEJ… (More)
