Abstract
Removal of proteins from the surface of medical equipments are attempted using oxygen plasma produced by RF discharge. FIIR spectra indicate that the bonds of C-H and N-H in the casein protein are reduced after irradiation of oxygen plasma. Also, the second order structure of a protein such as alpha-helix and beta-sheet are modified by the oxygen plasma. Complete removal of protein as remnants on the medical equipments requires several hours avoiding the damage to medical equipments.
