Enhanced Bactericidal Activity of Green Synthesized Gold Nanoparticles from Neptuniatriquetra

Since the last decade, enormous research in developing biocompatible materials for biomedical applications at the Nanoscale level emerged as an excellent essential research factor globally. In this context, in the present study contemplated for developing a novel nano materials which was synthesized in a green approach way using aqueous extracts of Neptunia triquetra and assessed for antibacterial activities against both Gram-positive and Gram-negative bacteria. Initially the antibacterial efficiency of Neptunia triquetra was assessed for different solvent extracts and compared with synthesized gold nanoparticles. A total of 6 bacterial strains viz. , Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas, and Staphylococcus aureus were used in the present study. The results demonstrated that the medicinal plant Neptunia triquetra is having high antibacterial activity. Interestingly, there is enhanced antibacterial activity of gold nanoparticles.
