ABSTRACT

Rosemary leaf extract (RMLE) was employed for the eco-friendly biogenic synthesis of copper nanoparticles (CuNPs@RMLE). The copper nanoparticles CuNPs@RMLE were characterized by X-ray fluorescence (XRF) and Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectroscopy in solid state. The antibacterial effectiveness of CuNPs@RMLE was assessed against Gram-negative strains, Pseudomonas aeruginosa (P. aeruginosa) and Escherichia coli (E. coli), as well as Gram-positive strains as Staphylococcus epidermidis (S. epidermidis) and Staphylococcus aureus (S. aureus). It is compared with the corresponding effectiveness exhibited by RMLE and copper(II).
