Effect of Silver and Graphene Oxide Nanoparticles on the Growth Behaviour of Escherichia Coli

Abstract

The antibacterial study using nanoparticles (NPs)have many advantages such as the use of alternate of antibiotic-resistant bacteria. Although much information have been garnering, many more is still required. In this investigation, Escherichia coli was cultured in standard LB nutrient broth with two different NP species, Graphene oxide and Silver NPs under varying concentration. The growth of bacteria was expressed by measuring of the culture absorbance at 600 nm. The results demonstrated that silver NPs inhibited the bacterial growth, while Graphene oxide (GO) showed the enhancement of bacterial growth.
