Nanoparticles are particles that are between the size of 1-100 nanometers. Gold nanoparticles in particular have been studied for use in medical science. The goal of this research is to test the toxicity of gold nanoparticles on Escherichia coli and Staphylococcus aureus. Data was collected by mixing gold nanoparticle solutions with inoculated broth, then plating the mixture. Through this research it was found that gold nanoparticles were not toxic to the bacteria tested while gold (III) ions were, which indicates that the method of gold nanoparticle synthesis used is highly effective at using the gold ion reactants.
