| Synthetic protocol |
Metal solution is reduced to metal sol followed by its loading over a suitable substrate |
Metal ions are incorporated over the substrate and then reduced by a suitable reducing agent |
Metal electrolyte is reduced and stabilized by bioextracts, biomass, biologically derived compounds |
In vitro synthesized metal particles reduce the metal ions, using reductive physiology of a live cell |
