a Time-lapse DFM live cell images in a single A549 cell after treatment of glutathione ethyl ester (GSH-OEt) indicating the in situ release of 6MP from Au NPs. The arrow indicates the position where the Raman spectra were obtained. The Au NPs were incubated for 24 h prior to the GSH-OEt treatment. b The peak at 1258 cm−1 was monitored with time. The other vibrational bands of 6MP also showed similar behaviors. Raman spectra were obtained after a few minutes from the injection time of GSH-OEt. c Plot of decrease in the band intensities depending on the elapsed time after GSH-OEt injection. The error bar indicated the standard deviation of the three measurements. GSH-OEt and tripeptides were marked in black and red, respectively
