In this paper, a new nanostructured Au-TiO(2) particle was synthesised and employed for the construction of a label-free amperometric immunosensor for carcinoembryonic antigen (CEA) determination. The spherical Au-TiO(2) nanoparticles provided a good microenvironment for the immobilization of biomolecules, enhanced the surface coverage of protein, had large… CONTINUE READING
