Through synergistic combination of the nanomaterials with oil degrading bacteria, methods can ameliorate environmental damage due to the presence of oil in an area through increased activation of the bacteria as well as through removal of the oil.Type: GrantFiled: December 6, 2017Date of Patent: November 14, 2023Assignee: UNIVERSITY OF SOUTH CAROLINAInventors: Jamie Lead, Alan Decho
