Plant extracts as green reductants for the synthesis of silver nanoparticles: Lessons from chemical synthesis

Abstract

The increasing use of silver (Ag) nanoparticles (NPs) in daily-life applications, elec-tronics, or catalysis calls for green and cost-efficient synthetic methods. Ag NPs are used especially in biomedicine because of their antibacterial, antifungal or anticancer properties. The chemical synthesis allows tuning parti-cle morphology, size and crystallinity, but requires toxic and hazardous chemicals. Bioinspired synthetic protocols have shown promise to mini-mize environmental impact biological protocols for the synthesis of Ag NPs lack control on morphology and crystallinity. This review briefly compiles the chemical synthesis of Ag nanoparticles and contrasts it with “green” protocols based on lessons learnt from chemical synthe-sis. The synthesis of Ag NPs with different plant extracts and the associated phytomol-ecules, their chemical and biological effects and their effect on particle synthesis are described and put in perspective to improve green protocols. The surface func-tionalization of Ag NPs by phytomolecules and mecha-nisms of their biomedical applications are summarized.
