In recent years, interest in the development of novel drug delivery systems using nanoparticles has gained more attention. The nanoparticles offer several advantages over other conventional drug delivery systems. Nanoparticles have gained importance in technological advancements due to their modifiable physical, chemical and biological properties with improved performance over their bulk foils. Nanoparticles can simply move in the body due to their small size and reach to complex organs through diverse routes. The high stability and controlled drug release make nanoparticles the most suitable drug delivery system. Synthesis of metal nanoparticles using plant extracts is one of the most simple, convenient, economical, and environmental-friendly methods that mitigate the involvement of toxic chemicals. Hence, in recent years, several eco-friendly processes for the rapid synthesis of silver nanoparticles have been reported using aqueous extracts of plant parts such as the leaf, bark, roots, etc. Extracts of a diverse range of plant species have been successfully used in making nanoparticles against pathogenic microbes. This capacity by plants to intrinsically utilize their organic processes to reorganize inorganic metal ions into nanoparticles has thus led to extensive studies into this area of biochemical synthesis and analysis. This review shows the importance of rapid screening of plant-based microbial agents and enhancing their activities to understand the role of nanoparticles of plant extract against microbial pathogens. |
