a Transmission electron microscopy (TEM) image of SnSNPs and size measurement. Experiment was repeated two times independently with similar results. b XRD pattern of SnSNPs. c High-resolution TEM image of SnSNPs. Experiment was repeated two times independently with similar results. d TGA of SnSNPs and SnSNPs@PEG. e FTIR spectra of SnSNPs and SnSNPs@PEG. f Hydrodynamic size of SnSNPs@PEG on different days measured by dynamic light scattering, data are presented as mean ± SD (n = 3).
