CuO is a known antibacterial compound. It is also known that doping of Zinc ions into CuO increases the antibacterial activity. In my research, Mg-doped CuO nanoparticles are synthesized and simultaneously deposited on cotton fabric, using ultrasound irradiation. With this method, Copper acetate and Magnesium acetate undergo hydrolysis under basic conditions, in order to form the oxide compound. The optimization of the processing conditions, the specific reagent ratio, and the precursor concentration results in the formation of uniform nanoparticles, with a length range of 100-300 nm and width range of 80-250 nm. The antibacterial activity of the Mg-doped CuO in a colloidal suspension or deposited on the fabric, is tested against Escherichia coli (Gram negative) and Staphylococcus aureus (Gram positive) bacteria.
