This powerpoint presentation outlines information on the environmental concerns and opportunities of nanotechnology in relation to: applications, enhanced or new capabilities to address existing and future environmental problems; and, implications, create the information needed to use nanomaterials in an environmentally responsible and sustainable manner The CBEN Systems Goal is to develop effective water treatment systems that exploit engineered nanoparticles. The CBEN Societal Driver is to enable effective risk management for emerging nanotechnologies. Topics covered include: disinfection and biofouling control; C₆₀ (buckminsterfullerene); nC₆₀: Environmentally Relevant; nC₆₀ is Bactericidal (E. coli assay); nC₆₀ as a potent antibacterial agent; possible toxicity mechanisms; E. coli permeability using flow cytometry; factors affecting nC₆₀'s toxicity to bacteria; dose response curve for Fullerenes; NOM reduces bioavailability and toxicity of nC₆₀; and, reduction of biofilm formation by nC₆₀. Includes figures.
