The combination of ZnO and PDA results in a change of optical properties of. coli of both ZnO−Ag nanohybrids and their nanocomposite coatings, two antibacterial tests have been carrieried out. In this work, we report the synthesis of ZnO thin films via two simple and low-cost synthesis routes, i. Zinc oxide nanoparticles (ZnO-NPs) have piqued the curiosity of researchers all over the world due to their extensive biological activity. 1 wt%, 0. The pumping source was a point transverse electric wave (380 nm to ∼ 400 nm) source located between the ZnO nanowire (centre one) and the ZnO film, which corresponds to the p-n junction active.
