Abstract
In the present study Keratin nanoparticles were synthesised from chicken feathers. The structure and morphological characteristic of keratin nanoparticles were investigated by using SEM and XRD. X-ray crystallography showed the crystalline peak at 37.5 degree, which indicates the presence of keratin nanoparticle. Crystalline size of the keratin nanoparticle was found to be 79.6 nm. Anti oxidant activity of keratin nanoparticles was found to be 78 % and 88% by DPPH and Superoxide method respectively. Antibacterial activity of keratin nanoparticle was identified by well diffusion method against bovine mastitis, Staphylococcus aureus isolated from milk and E.coli. The zone of inhibition was found to be 11 mm in diameter against Staphylococcus aureusand 9.5 mm against E.coli at 100µg/ml concentration.
