College of Environment, Hohai University, Nanjing, Jiangsu 210098, China) Abstract: Manufactured nanomaterials have been widely used in life because of their unique physical and chemical properties. The environmental behaviors and biological safety of manufactured nanomaterials in water had become a hotspot in research of environmental science. The effects of manufactured nanomaterials in water-biofilm system and its influencing mechanisms are the key scientific problems, which are urgent to be solved. Thi
