GREEN SYNTHESIS AND ANTIMICROBIAL ACTIVITY STUDIES OF CURCUMINANILINE FUNCTIONALIZED ZINC OXIDE NANOPARTICLES AND COMPARATIVE STUDIES WITH ITS NON-FUNCTIONALIZED FORM

Biofunctionalization of nanoparticles is an advancement of current nanotechnology and biotechnology fields. Developing biocompatible progressive functional materials possess antimicrobial properties could be hopeful for environmentally benevolent applications. Biofunctionalization of nanomaterials is one such topic to produce the non-toxic and more efficient antimicrobial agents. The present study describes a synthesis method of bioactive curcuminaniline functionalized zinc oxide nanoparticles in the eco-friendly methods and comparative studies of those were undertaken against non-functionalized zinc oxide nanoparticles. The synthesis process was carried out through a simple green methodology. Synthesized nanoparticles were analyzed for antibacterial activity by using disc diffusion method against two gram-positive bacteria and two gram-negative bacteria and antifungal activity by using agar well diffusion method against four funguses. Synthesized materials were characterized by UV- Vis, FT-IR, SEM and TEM techniques. The synthesized zinc oxide nanoparticles were in the range of 46 nm and the biofunctonalized nanoparticles were about 100 nm. The antimicrobial activities of those were showed appreciable inhibition zones against S.typhi, B.subtilis, A.niger and T.simii species.
