How Are Nanoparticles Synthesized Using Biological Methods?
Biological methods for nanoparticle synthesis often leverage the innate capabilities of microorganisms, plants, or enzymes to produce nanoparticles. These methods can be more environmentally friendly and cost-effective compared to traditional chemical synthesis.
Microbial Synthesis: Bacteria, fungi, and algae can be employed to synthesize nanoparticles. For example, certain bacteria can reduce metal ions to form metal nanoparticles. Plant-Mediated Synthesis: Plant extracts containing natural reducing agents can be used to convert metal ions into nanoparticles, offering a green and sustainable method. Enzyme-Mediated Synthesis: Enzymes can catalyze the formation of nanoparticles with specific shapes and sizes, providing precise control over the synthesis process.
