Iron is essential to microbial life, but it can be scarce in many environments. So bacteria gather this nutrient and stash it away within intracellular compartments they can draw from when external sources dry up. Now, scientists have repurposed a recently discovered iron-storing compartment in bacteria, engineering the microbes to store silver instead of iron in order to produce silver nanoparticles for industrial uses (ACS Synth.
