Antibacterial Activity of Copper Nanoparticles Synthesized by Using Peumus boldus Leaf Extract

İngilizce (OpenAlex)

The green synthesis method, which is one of the methods of obtaining nanoparticles; It is a preferred method because it is simpler, environmentally friendly, economical and turns into a product in a short time. In this study, it was aimed to investigate CuNp synthesis possibilities and antimicrobial activity of this Np by using the extract of Peumus boldus, an endemic plant. The synthesized CuNps were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrophotometer (FTIR) and X-ray diffraction (XRD). It was determined that the NPs synthesis was successful, and the overall geometry was spherical; besides, the diameters were less than 50 nm. The antibacterial activity of CuNps was tested by the broth dilution method. It was observed that CuNps synthesized with Peumus boldus extract used at 125 to 250 µgr/ml concentrations suppressed the viability of E. coli and S. aureus by 60%.
