pH Responsive Curcumin/ ZnO Nanocomposite For Drug Delivery

Curcumin is recognized as an important natural biomaterial which has a wide range of biological importance, unfortunately it lacks in bioavailability predominantly due to its poor aqueous solubility. The intention of the present investigation was to develop a novel nanocomposite of curcumin with ZnO nanoparticle in order to improve its aqueous-phase solubility and develop its efficiency on microbes and cancer cells. Therefore, we have constructed an aqueous solvable curcumin/ZnO nanocomposite from the insoluble commercial curcumin and poorly soluble ZnO nanoparticles, consequently enhancing its biological importance. The synthesized ZnO nanoparticles, nanocurcumin, and the nanocomposite were analyzed with transmission electron microscope (TEM), and X-ray diffraction (XRD) along with spectral techniques. The calculated average particle size of ZnO nanoparticle and nanocomposite from XRD was found to be 21.44 nm and 24.66 nm respectively. The TEM image reveals that this new nanocomposite
