(A) TEM images and particle size distribution maps of GAGQD. (B) HRTEM of GAGQD. (C) High-resolution x-ray photoelectron spectroscopy data of C1s for GAGQD. (D) UV-vis absorption spectra of GQD and GAGQD. a.u., arbitrary units. (E) Scanning electron microscopy (SEM) images of siRNA-GBSA(CHI/TA)5 NPs. (F and G) Encapsulation efficiency of siRNA or GAGQD in siRNA-GBSA NPs. (H and I) •O2− elimination activity and •OH elimination activity of GBSA NPs and GBSA(CHI/TA)5 NPs. (J and K) •O2− elimination activity and •OH elimination activity of GQD and GAGQD. (Data are presented as the mean ± SD; *P < 0.05, **P < 0.01, and ****P < 0.0001).
