Abstract: A yellow compound Curcumin, known for its superior biological and pharmacological properties obtained from the roots of plant Turmeric. The curcumin is insoluble in aqueous media therefore it’s applications are limited. So this research work aims to increase its solubility in water medium.
In this silver nanoparticles were synthesized by wet chemical method and capped with curcumin. The Polyvinyl Pyrrolidone (PVP) is used as a binder between silver nanoparticles and curcumin. The synthesized conjugate is characterized by UV Vis spectroscopy, FTIR, and FESEM. The size of conjugate is found in the range of 40-65 nm as confirmed by FESEM. Further the conjugation of curcumin with silver nanoparticles showed good antibacterial activity against P. aeroginosa, E. coli and B. cereus.
