Abstract

Silver nanoparticles (AgNPs) are highlighted by researchers for their special properties. This review explores the green synthesis processes of Nano silver using natural sources and examines their practical applications. Green synthesis uses plant extracts and microorganisms such as bacteria, fungi, and algae. These methods are environmentally eco-friendly and economical and avoid harmful chemicals. The synthesis is primarily the reduction of silver ions to AgNPs through biologically reactive compounds present in natural sources. The green synthesis approach is more sustainable compared to chemical methods, which reduces costs and enhances environmental sustainability. Silver nanoparticles have applications in various fields. However, stable silver nanoparticles that can be widely applied are still a challenge for researchers despite the great diversity of different biological sources, whether from plants with their various parts or microorganisms. In this research, 45 biological sources for the production of AgNPs were identified. Therefore, green synthesis methods for Nano silver from natural sources represent a promising research area that requires significant collaborative efforts. Also, continuous advances in manufacturing techniques and scientific research are expanding the applications of silver nanoparticles into new and unexpected areas.
