a TEM image of MYnano, scale bar = 300 nm. b Dissolution of MYnano and MY. c Hydrodynamic size distribution of MY@PLGA and MYnano. d–e SP and SP@MYnn (d), along with their SEM images (pseudo-color) (e), scale bar = 1 µm. f UV-visible spectrum. g Zeta potential (n = 6 independent experiments). h Fluorescence and 3D images of SP@DiOnano (DiO-labled SP@MYnn), scale bar = 10 µm. i Diameter of the DiO-nano coating (n = 6 independent experiments). One-way ANOVA with Tukey’s post hoc test was used for comparisons among multiple groups, SGF vs. PBS, P  =  0.9945; SIF vs. SGF, P  =  0.0082; SCF vs. SGF, P  =  0.0102. j Another fluorescence images of SP@DiOnano under different growth conditions and 3D reconstruction, scale bar = 5 µm. k SEM images (pseudo-color) of SP@MYnn after treatment with SGF, SIF, or SCF, scale bar = 600 nm. The data show means + SD (* < 0.05, ** < 0.01, n.s., no significance). Source data are provided as a Source Data file.
