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) and the lower esophageal sphincter of patients
pH值生效!描述了一种比例式双光子(TP)探针(NP1,请参见方案),该探针具有显着的TP作用横截面,高光稳定性,可忽略的毒性,并且可以通过双光子显微镜估计活细胞和人体组织中的pH值。NP1可以检测患有和不患有食管炎的患者的胃食管连接处(GEJ)和食管下括约肌的活细胞之间的pH差异(见图)。
