Green Synthesis of Nanoparticles and Their Biomedical Applications: A Review

In the arena of material sciences, one of the burning topics for research has been biogenically synthesizing nanoparticles (NPs) from plant derivatives and studying their applicability to be used as sustainable catalysts. The contemporary work happening on nanocatalysts focuses on the scope of application of green catalysts. For devising a technology that is ecofriendly as well as rapid, it seems a very viable option to biogenically synthesize NPs from plants. The potential that plants have in synthesizing these NPs has been mostly an unexplored venture, and the massive plant diversity is the reason for this is the lack of exploration. The NPs have antioxidant, antibacterial, and antimicrobial characteristics, which make them suitable candidates for application in different biomedical applications. This review begins with a discussion about the different natural products that are used for NP synthesis and goes on to discuss the factors that affect the synthesis. The authors have aimed to provide detailed information about green NPs and their applications in different biomedical areas. Existing literature on NP-based biomedical applications focuses more on synthetic NPs, and we hope that this review will help the readers to formulate a fresh perspective by concentrating their interests toward naturally synthesized NPs and their applications.
