antibacterial activity of cuo - cellulose nano rods depends on anew green synthesis (cotton)

In this study cuo nano sheets were prepared using the cellulose extracted from green synthesis (cotton) as a novel me project. structural properties were examined using x-ray diffraction (xrd), field emission scanning electron microscopy (fesem), and ultra violet (uv-vis). the optimum copper oxide peak was at 2 theta 35.44o corresponding to ( 1 11) while for the cellulose was 22.8o corresponds to (002). fesem images of cuo nano sheets were relatively homogenous with diameters less than 30 nm. the uv-vis for cuo-cellulose nano rods was observed at 350-360 nm, which is higher than of pure cuo nano sheet. the energy band gaps were 3.20 ev and 3.30 ev of cuo and cuo-cnr respectively. finally antimicrobial activities of samples have been investigated against the gram positive (pneumonia) and gram-negative (pseudomonas). the maximum antibacterial activities against the gram positive (pneumonia) of cuo nano sheet and of cuocellulose nano rods are 16 mm and 19 mm respectively. the maximum antibacterial activities against the gram negative (pseudomonas) of cuo nano sheet and of cuo- cellulose nano rods are 30 mm and 33 mm.
