a Time-lapse DFM live cell images in a single HeLa cell after treatment of glutathione ethyl ester (GSH-OEt) indicating the in situ release of 6TG from Au NPs. The arrow indicates the position where the Raman spectra were obtained. b The strongest peak at 1291 cm−1 from 6TG was used. c Plot of decrease in the band intensities depending on the elapsed time after GSH-OEt injection
