Due to the toxicity related to the conventional chemical synthesis and high cost of physical synthesis of silver nanoparticles, green synthesis which consist of microbial and plant mediated synthesis of AgNPs should be promoted and considered. This method is based on the use of non-toxic, non-hazardous and biobased compounds as reducing agents and reagents which are biodegradable. In this microorganism or plant extracts are used as reducing agents which traditionally have higher biodegradability and bioavailability than conventionally used chemical reagents . More research should be conducted to have a better understanding of the mechanism of plant mediated synthesis of AgNPs. Plant extracts can naturally reduce heavy metal ions such as Ag + and can convert it to metallic Ag 0 which then can be used to synthesize silver nanoparticles . These plant compounds are cost effective as the reagents used can act as both reducing and capping agents therefore no additional chemical reagent like DMF or PVP is required, thus reducing the cost and toxicity of AgNPs as these chemical reagents used in conventional methods can be hazardous to human health and environment. No additional medium is required to synthesize AgNPs in plant mediated synthesis as nanoparticles are synthesized and nucleated within the plant tissue .
