P1.5.5 Study of TiO2 NWs-based FET immunosensor: effect of surface immobilization methods

Chi-Chang Lin, Yung-Ming Chu & Hsien-Chang Chang
Immobilization of biomolecule on biosensor surface is an important issue for develop higher sensitivity immunosensors. Recognition elements can be modified on material surface through chemical conjugate, physical adsorption and, polymer entrapment etc. Although most of these methods are well established, none of them can perform both in situ immobilization of biomolecues and be easily established. In this study, anti-rabbit IgG (1oAb) is encapsulated by a cyclic-voltammetry for electropolymerization of pyrrole propylic acid (Pa) on self-designed...
