Deinococcus radiodurans was discovered in 1956 by scientists accidently, after a can of corned beef had been treated with radiation in order to kill any harmful microorganisms that might have been present in the canned meat. Since its accidental discovery, D. radiodurans has been intriguing scientists with is astonishing resistance to ionizing radiation, UV radiation, electrophilic mutagens, oxidizing agents, and desiccation. This gram-positive bacteria usually forms in spherical pairs or tetrads; it is not only able to survive gamma radiation greater than 2,000 DSBs (per multigenomic cell), but it is also able to flourish endlessly while being treated with chronic radiation. This extremely resistant bacterium is considered to be a mesophile,

Naomaterials are said to act as a connecting bridges between atomic/molecular structures and bulk materials. Silver nanoparticles (AgNPs), in particular, have intrigued scientists with its potential various uses in the medical field. “The strong antibacterial activity against a wide range of pathogens and their potential in wound healing are amongst the most import usages of AGNPs in the medical field”, (International Journal of Nanomedicine IJN, …show more content…
Three differ assays were used and tested in this experiment: Antibacterial, anti-biofouling, and cytotoxicity assay (anticancer). Each assay used different microorganisms that were grown and tested in the lab, and were then introduced to various levels of synthesized AgNPs-- growing D. radiodurans strain R1 ATCCBAA-816, without the presence of oxygen in “TGY (0.5% bacto yeast extract, 1% bacto tryptone, 0.1% glucose) broth with agitation (160 rpm), or on TGY-agar plates (1.5 % bacto agar) 32 degrees Celsius,” (International Journal of Nanomedicine IJN,
