Characteristics of the SH NPs and SH/HA NPs. A SH NPs and SH/HA NPs were prepared using the lyophilization–hydration method. B Transmission electron microscopy (TEM) images of SH NPs and SH/HA NPs (red arrow). Samples were negatively stained with 2% uranyl acetate (UA) before imaging. Scale bar = 200 nm. C Size distribution of SH NPs and SH/HA NPs. D X-ray diffraction patterns of SN38, SH/HA NPs, SH NPs, HA, and HSA. E Storage stability of SH NPs or SH/HA NPs was determined by solving the re-lyophilized SH NPs or SH/HA NPs in 1 mL ddH2O at 1, 10, 20, and 30 days (n = 3)
