Abstract

We report on the process of synthesizing copper nanoparticles Cu Nps for a short reactive time by chemical reduction method with a support of CTAB reductive agent. Their properties were determined by ultraviolet-visible UV-Vis absorption spectrum, the X-ray XRD analysis, Fourier transform infrared spectroscopy FT-IR, and Transmission Electron Microscopy TEM images. The antifungal activity of Cu Nps was evaluated by testing against Fusarium sp. The Cu Nps were obtained with the average size in the range of 20–50 nm having spherical shape. The survey shows that when Cu Nps were used at 450 ppm concentration in 9-day incubation, 93.98% of fungal growth was inhibited.
