This study investigated the potential of using Cynodon dactylon aqueous leaf extract to synthesize copper nanoparticles (CuNPs) and their antibacterial and dye degrading capabilities. The results showed that the green synthesized CuNPs exhibited significant antibacterial and dye degrading potentials.
The copper nanoparticles (CuNPs) synthesizing potential of Cynodon dactylon aqueous leaf extract and their antibacterial as well as dye degradation potentials were investigated. The synthesized CuNPs was initially characterized by gradual colour change from dark brown to blue in colour and then found absorbance peak at 469 nm. Furthermore, the SEM and DLS analyses showed that biosynthesized CuNPs were spherical in shaped and size ranging from 120 to 129 nm. The FTIR spectrum confirmed the presence of flavonoids, alkaloids, terpenoids, and phenols, which involved in the reduction, capping, and stabilization of CuNPs. This green synthesized CuNPs also demonstrated remarkable antibacterial activity against the bacterial pathogens such as Escherichia cob, Bacillus subtilis and Staphylococcus aureus and Klebsiella pneumoniae. This green synthesized CuNPs exhibited considerable dye degrading potential in the following order as methyl organge > methyl red > Erichrome black T dyes in the presence of sunlight through photocatalytic degradation process. These results conclude that C. dactylon aqueous leaf extract mediated nanoparticles possess remarkable antibacterial and dye degrading potential.
