Abstract

Abstract : Copper(II) were immobilised onto medical titanium surface by polydopamine (PDA) chelating, to build intrinsic antibacterial implant materials for inhibition of implant infection. A scanning electrical microscope showed that the modified titanium surface morphology was a porous nanostructure. An energy dispersive spectrometer showed the existence of Cu, and X-ray photoelectron spectroscopy results further confirmed that the immobilised copper element was in the form of Cu(II). Bacteria plate colony counting results showed that modified titanium surface had decent antibacterial property, matching the ion release outcomes. It could be conclude that the PDA assisted Cu(II) immobilisation was an efficient and effective method for antibacterial modification of titanium.
