Both nCuO appeared with an irregular morphology

commercial CuO presented a mean diameter of 34,38> 0,76 nm while and a broad size distribution sonochemical CuO has a mean of diameter 24,01> 0,76 with a NP size distribution between 15 and 30 nm

sonochemical CuO NPs are crystallites with more defects and less organized structure than commercial CuO different ability to produce ROS in a cell free system sonochemical CuO NPs are more toxic to the bacteria…
