Elimination of bacteria and other microbes effectively is important to our daily life and a variety of medical applications. Here,\r\nwe introduce a new kind of trimolybdate nanowires, namely Ag2-x(NH4)xMo3O10 �· 3H2O, that carry a large amount of Ag atoms\r\nin the lattice and Ag-rich nanoparticles on the surface. These nanowires can eliminate bacteria of E. coli, Staphylococcus aureus,\r\nand unknown microbes in raw natural water with high efficiency. For example, they can inactivate more than 98% of E. coli with\r\na nanowire concentration of only 5 ppm in the solution. The excellent sterilization performance is attributed to the combined\r\neffects of Ag ions, Mo ions, and Ag-rich nanoparticles of the Ag2-x(NH4)xMo3O10 �· 3H2O nanowires. These nanowires are not\r\ndissolvable in deionized water but can be dissolved by the metabolic materials released from bacteria, making them attractive for\r\nmany biological applications.
