A simple method for the detection of metal ions in solution is proposed, using Shewanella oneidensis, which has the ability to reduce metal ions into metal nanoparticles on the cell surface. The method can be used to identify metal ions in solution using the light-scattering characteristics of the metal nanoparticles formed on the cells.
