Recent Developments and Applications in Plant-extract Mediated Synthesis of Silver Nanoparticles

Abstract

Green synthesis is a widely used for the preparation of silver nanoparticles. The use of plant extracts for these syntheses has become common in recent years because they are nontoxic, inexpensive, and widely available. Phytochemicals such as terpenoids, flavones, ketones, aldehydes, amides, and carboxylic acids are the primary active ingredients for nanoparticle synthesis. Reaction temperature plays an important role during the reduction process as it influences the reaction time, particle size, and the intensity of the surface plasmon resonance peak. This review presents an overview of recently developed and reported silver nanoparticle syntheses using plant extracts. The role of temperature in nanoparticles synthesis and potential applications has been reviewed. A brief description of the reaction mechanism and nanoparticle characterization techniques are also included.
