Scholarcy highlights

  • Nanomaterials are of great scientific and commercial interest
  • The magnetic resonance+ spectra of the Extracellular polymeric substances before and after reaction with Ag+ revealed that the antibacterial activity of Ag ions was mitigated because the synthesized Ag NPs in the EPS were not hemiacetal groups of the sugars in the EPS contributed to Ag NPs synthesis
  • AsPurification many organic from theby cell components are present in the NPs solution synthesized by Microorganisms microorganisms, purification and isolation NPs from such contaminants are necessary for application
  • We have reviewed the synthesis of metal NPs by microorganisms
  • Over the last half-century, various metal NPs have been synthesized by numerous microorganisms
  • The active substances for their synthesis were identified from microorganism extracts
  • Such genetically control methods can regulate the size and shape of metal NPs. As many biological molecules exist in the microorganism suspension, it is difficult to isolate metal NPs. analyses of molecular mechanisms can reveal the active molecules binding to the surface of metal NPs. If these active molecules may be useful for the applications such as biocompatibility, biomarker, and anti-cancer effects, we can use these metal NPs as high functional organic–inorganic hybrid materials
