Chase is a sophomore researcher at the Advanced STEM Research Laboratory working in the realm of epidemiology. Globally, money is the most frequent item passed from hand to hand. Tests on United States banknotes have proven that diseases/viruses such as Staphylococcus aureus, Escherichia coli, and Salmonella sp. can cause excessive sweating, nausea, and diarrhea, and can survive on US banknotes. A synthetic plastic with with .05g of copper layer was added around banknotes. This reduces the chance of bacterial/viral infection. Thirty samples of $1 American banknotes, and 30 samples of synthetic plastic with .05g of copper wrapped around the American banknotes. A cotton swab sampled each dollar banknote and was transferred to a petri dish for cultivation. This process was repeated for the synthetic plastic wrapping material. After three days, the average amount of bacteria cultured from the US banknote was compared to the synthetic banknote wrapping. Future studies will investigate different banknotes from various countries.
