(A) The fluorescence emission spectra of pristine DOX at different concentrations and of DOX-PEG500-epoxy, AuPEG2000-DOX, iAuPEG2000-DOX, AuPEG2000-TAT-DOX, iAuPEG2000-TAT-DOX at DOX concentration of around 0.2 mg/mL; (B) the fluorescence emission spectra of DOX-PEG500-epoxy at different DOX concentrations; (C, D) the variation of the fluorescence peaks vs. DOX concentration of the studied systems at λem = 590 nm and λem = 556 nm respectively; all spectra were registered at λex = 480 nm.
