Physical-chemical characteristics of CuONPs used in this study. A The TEM image of CuONPs. Note that the CuONPs were spheroid or cubic. Aggregation of CuONPs was observed. Scale bar, 100Â nm. B The diameter of CuONPs was calculated according to the TEM results. Note that the size of CuONPs was about 50Â nm. C The SEM image of CuONPs. Scale bar, 100Â nm. D FE/SEM-EDS was applied to determine the composition of CuONPs. E The hydrodynamic diameters of CuONPs were determined by DLS analysis
