Abstract
Anisotropic gold nanoparticles (Au NPs) have been synthesized via a green route with the aid of Malva parviflora (M. parviflora) extract. Their UV-vis-NIR spectra exhibit a near infrared absorption feature, which is due to the one-dimensional growth of Au NPs. The images of transmission electron microscopy (TEM) show that the Au NPs are triangular in shape. The formation of Au anisotropic nanoparticles was found to depend on the extract quantity. The Au NPs show good antibacterial activity against the Gram-positive bacteria Bacillus subtilis and Enterococcus faecalis.
