Green synthesis methods employ biological organisms or natural products to produce nanomaterials. Some common techniques include:
Plant Extracts: Utilizing phytochemicals from plants to reduce metal ions into nanoparticles. Microorganisms: Employing bacteria, fungi, and algae to biosynthesize nanoparticles. Natural Polymers: Using biopolymers such as chitosan and cellulose for the development of nanomaterials.
