Silver nanoparticles can be synthesized through various methods, including:
1. Chemical Reduction: This is the most common method, where a silver salt (e.g., silver nitrate) is reduced using a reducing agent like sodium borohydride or citrate. The choice of reducing agent and stabilizer affects the size and shape of the nanoparticles.
2. Physical Methods: Techniques such as laser ablation and evaporation-condensation can produce silver nanoparticles without the use of chemical reagents, resulting in purer particles.
3. Green Synthesis: Utilizing biological methods, such as plant extracts and microorganisms, can produce silver nanoparticles in an eco-friendly manner. This method is gaining popularity due to its sustainability.
