Green Synthesis, Characterization and Antimicrobial Activity Studies of Salicylalchitosan Biofunctionalized Copper Oxide Nanoparticles

摘要

In the present work, we reported the green synthesis of biofunctionalized copper oxide nanoparticles with salicylalchitosan derived from chitosan. Salicylalchitosan, copper oxide nanoparticles and biofunctionalized nanoparticles were characterized by UV-visible, FT-IR. SEM and TEM techniques and antimicrobial activity studies of those were undertaken. The size of synthesized copper oxide nanoparticles was in the ranges around 60 to 100 nm and bio functionalized particles were about 100 nm. The antimicrobial activities of biofunctionalized copper oxide nanoparticles were observed higher inhibition activity than the non-functionalized nanoparticles and salicylalchitosan against standard microbial species.
