When glutathione was adsorbed onto the AgNPs surface, the IR signals at 1,712, 1,660, 1,536, and 1395 cm 1 were significantly enhanced, and the absorption peaks corresponding to the carboxylate COO stretching vibration moved to 1,716 and 1,398 cm 1 , respectively
Detection was carried out with positive polarity, in selected reaction monitoring (SRM) mode, selecting the following ions: AX 366.4, 114.0 (22eV), 349.0 (6eV)
