Figure 2

SEM images of as-synthesized ZnO nanosphere (A) and ZnO/L-Cys@CFX (B). The inset shows a high magnification image of the same. EDX spectra (C) and elemental mapping (D) of ZnO in the nanocomposite. (E) XRD peaks of synthesized pure ZnO sphere and (F) ATR-FTIR spectra of (i) L-Cys powder; (ii) ZnO/L-Cys, and (iii) ZnO/L-Cys@CFX.
