Characterization of lipidosome. A. A schematic diagram of the synthesis of DTP NPs. B. The ¹H NMR spectra of DP (DSPE-PEG₂₀₀₀) and DTP (DSPE-TK-PEG₂₀₀₀). C. The representative TEM image of DTP@KA NPs. Scale bar = 100 nm. D. The average size. E. The average zeta potential. F. The stability of DTP@KA NPs in size and zeta potential for 7 days. G. The drug release curve of DTP@KA NPs stimulated by H₂O₂. H. The UV–Vis–NIR absorption spectra. Data represent the mean ± SEM of at least three independent experiments
