PREPARATION AND EVALUATION OF GEL INCORPORATED WITH SILVER NANOPARTICLES FROM TAGETES ERECTA

Nanotechnology is one of the most rapidly developing fields of study. Because of their critical uses in biotechnology, bioengineering, textile engineering, water treatment, and metal-based consumer items, the synthesis and characterization of metal nanoparticles such as silver, gold and platinum are growing topic of research. It has been established that silver metal possesses antibacterial properties since ancient times. Due to their unique features and wide range of uses, silver nanoparticles (AgNps) are used. Infections in open wounds and chronic ulcers are treated with silver nanoparticles as well as medical devices, cosmetics, electronics and household appliances, Catalysis, bio sensing, imaging. However, in most of the methods precarious chemicals and low material conversions and high energy requirements are used for the preparation of nanoparticles. So, there is a need to develop high-yield, low cost, non- toxic and environmentally friendly procedures. In such a situation biological approach appears to be very appropriate. Natural material like plants, bacteria, fungi, yeast are used for synthesis of silver nanoparticles. Key Words: Targets erecta, silver nanoparticles, antimicrobial activity
