Description
The science of nanotechnology has seen incredible progress in the recent years and has opened up new avenues of possibilities in the field of engineering, biomedical science, drug-delivery, chemical industry and environmental research process. In this regard, ‘green’ synthesis has gained widespread attention as a reliable, sustainable, non-toxic, economical and eco-friendly alternative for nanomaterial production. Green synthesised nanoparticles has attracted considerable worldwide attention in development science and treatment of any disease. Green synthesis involves the use of biological materials including whole plants, plant tissues, plant extracts, phytochemicals (flavonoids, terpenoids, alkaloids, aldehydes), microorganisms and algae for the synthesis of nanoparticles. The bioactive properties of the formed nanomaterials like anti-bacterial, anti-oxidant, anti-inflammatory, wound healing and anti-cancer has also been evaluated several times. Besides therapeutic activity, green synthesized nanoparticles have also been found to possess several industrial applications such as the improvement of thermal and storage stability of enzymes by immobilization techniques using flavonoid-functionalized metal nanoparticles. Along with the numerous benefits of using natural products for nanoparticle formation, there are also several challenges in obtaining particles with homogenous size distribution and morphology. Several parameters like temperature and pH of the system, concentration and nature of the active phytochemical need careful consideration.
