This study used the biomolecule, eumelanin, as an agent for the reduction of metal ions. Our results demonstrate the effectiveness of synthesizing diverse metal nanoparticles through the use of recombinant E. coli expressing Rhizobium 10 65 Fig. 1 EuMel from R. etli mediates the synthesis of gold nanoparticles. (A) Photograph of solutions in the presence or absence of 1 mM L-DOPA and Au 3+ , respectively. (B) TEM image of gold nanoparticles synthesized by EuMel. Scale bar: 20 nm. (C) TEM images of R. etli cells. Cells were incubated with or without 1 mM L-DOPA for 12 h. Subsequently, 2mM 70 of Au 3+ or water was added. Scale bar: 200 nm.
