Green synthesis approach for nanoparticle is environmental friendly, non-hazardous and the nanoparticles have shown enhanced biocompatibility for application in healthcare. Previous reviews have mentioned about green synthesis methods for nanoparticles and their biological activities. This review not only covers the general information about green synthesis of silver nanoparticles and characterization, but also focused on recent uses of various medicinal and nonmedical plants based AgNPs synthesis and their broad-spectrum antimicrobial and anticancer activities. In addition, this review emphasizes on elaborating underlying mechanism of anti-pathogenic microbial and anticancer activities of plant based AgNPs. Thus, present article provides a comprehensive analysis of plant-mediated synthesis of AgNPs and their potential applications in biomedical field including their mode of action and challenges in a single window.
