Nanotechnology deals with the production and usage of materials with nanoscale dimensions. The nanosized particles make an imprint in our daily lives and it has great importance in numerous fields of biotechnology, such as the food industry, medical, and industrial fields. Conventionally, metal nanoparticles are synthesized by chemical methods, which later on become accountable for various biological risks due to their general toxicity, engendering serious concern to develop environment-friendly processes. Green synthesis is the most fascinating, comparatively simple, and attractive alternative to chemical synthesis as it offers more advantages. The use of plant extracts for synthesis of NPs is potentially advantageous over microorganisms due to the ease of scaling up the biohazards and elaborates process of maintaining cell cultures. Nontoxic and ecofriendly secondary metabolites from plants are also used as reducing and capping agents. In this chapter, we provide comprehensive information about the current status of plant-mediated synthesis of metal nanoparticles, factors responsible for reduction of metal nanoparticle, and their applications. |
