This powerpoint presentation looks at bio- and nano-technologies for water treatment. The presentation first provides background information on bio- and nano-technologies, and then outlines prospective materials for the two technologies that includes: quantum dots; nanoparticles; sensors; microfabricated sensors; carbon nanotubes; Nano Zero-Valent Metal Iron (NZVM); nanotoxicity; and, microbial fuel cells. The second part of the presentation takes a look at the environmental nano- and molecular bio-technologies from the standpoint of: synthesis, characterization, and bioconjugation of NPs; optical and electrochemical detection; monitoring for human health risks of micropollutants, E. coli, and toxin producing algae monitoring; bioelectrochemical H2, bioelectrochemical cell (BEC), and photoelectrochemical H2 production; anaerobic fermentation; and, environmental NPs application (groundwater). Challenges include: safety concerns about the truth behind the facts of nanoparticles; system engineering related to nano and biotechnology for environmental technology; highly interdisciplinary nature of nanobio and environmental technology; and, a new class of nano-measurement requirements that enable a massive, easy, and quick detection and identification of nano-target. Includes figures.
