Biological Synthesis

There are mainly three types of approaches for the synthesis of nanoparticles: the physical, chemical, and biological approaches. The biological synthesis of nanoparticles utilizes bioactive agents, including plant materials, microbes, and various biowastes like vegetable waste, fruit peel waste, eggshell, agricultural waste, algae, and so on. The biological synthesis of nanoparticles has several advantages, including being straightforward, affordable, producing nanoparticles with high stability and biocompatibility, requiring little time, producing non-toxic byproducts, and being readily scaled up for large-scale synthesis.

Common Biological Synthesis Techniques

• Biological Synthesis with Microorganisms: Microbes use metal capture, enzymatic reduction, and capping to create nanoparticles. Use of microorganisms (especially marine microbes) for synthesis of metallic nanoparticles is environmental-friendly, fast and economical.
  • Biosynthesis by bacteria
  • Extracellular synthesis by bacteria
  • Intracellular synthesis by bacteria
  • Biosynthesis by fungi
  • Biosynthesis by actinomycetes
  • Biosynthesis by algae
  • Intracellular synthesis by algae
  • Extracellular synthesis by algae
• Biological Synthesis with Plant Extracts: Plant extracts are combined with a metal salt solution at room temperature to create nanoparticles. This method can be used to create nanoparticles of silver, gold, and many other metals.
• Biological Synthesis with Biomimetic: In the biomimetic approach, proteins, enzymes, cells, viruses, pollen, and waste biomass are used to synthesize nanoparticles.
  • Functional biomimetic synthesis
  • Process biomimetic synthesis
