Morphology and formation of SeNPs freshly synthesized in the presence of aqueous CTS. a TEM image of CTS-SeNPs and their appearance (inset). b The size distribution of CTS-SeNPs measured basing on TEM results. c Typical EDS spectra of CTS-SeNPs and their elemental composition. d TEM image of CTS-SeNPs after a 60-days preservation and photos of SeNPs in the absence or presence of CTS during storage at 25 °C (inset). Big arrows represent aggregated SeNPs while smaller ones represent free SeNPs
