Characterization of the theranostic rGO-AuNP nanocomposite. (A–C) TEM images of rGO-AuNP at different densities and magnifications. (D) Hydro dynamic distribution of the AuNPs and rGO-AuNP. (E) UV-vis spectra of the rGO-AuNP. (F) SERS spectra of the rGO, the mixture of AuNPs and rGO, and rGO-AuNP complex nanosheet.
