Release of SeNPs from SeNPs-CM in HCl solution. SeNPs-CM was mixed with HCl solution (pH 1.2). After 1–2 hrs, the mixture was filtrated by using a filter membrane (with the aperture size of 0.45 μm), and the filtrate was sampled for TEM observation and EDS investigation. (A) TEM image of SeNPs and (B) the details. (C) Typical EDS spectra obtained in Figure 2B (Area III versus Area IV).
