Fabrication system for surface modification of polystyrene beads by UV/Ozone treatment and its characterization
It is known that polystyrene must be chemically modified to make its surface enable to covalent cross-linking with protein. The aim of this study was to develop UV/Ozone treatment system and investigate the effects of treatment system on surface of polystyrene beads. The surface of polystyrene beads...
