Abstract


In recent years, metals and conductive polymers in the nanometer range consisting of metal / conductive polymer composite nanomaterials because of their special features and effects caused widespread concern . Such a high electrochemical activity and biocompatibility of composite nanomaterials has a good prospect in the field of electrochemical sensing and biosensing . In this thesis, the electrochemical deposition method modified with sulfonic acid doped polyaniline nanofibers ( nanoSPAN ) the matrix electrode surface were prepared Pt / nanoSPAN and Au / nanoSPAN two composite nano-materials , and based on the two composite nano- the materials were a series of studies , the two parts of the main research work are as follows : (1) the use of multi - potential step electrodeposition method was successfully prepared Pt / nanoSPAN , composite nanomaterials by scanning electron microscopy , cyclic voltammetry , Amperometric prepared Pt / nanoSPAN composite nanomaterials morphology, size and nature of the characterization and electrochemical impedance spectroscopy techniques . The composite nanomaterials modified electrode to build electrochemical sensing and biosensing platform to achieve a sensitivity of detection of CH3OH , H2O2 and DNA . (2) with four electrochemical deposition method were prepared the Au / nanoSPAN composite nano-materials and technology by scanning electron microscopy , cyclic voltammetry , electrochemical impedance spectroscopy and differential pulse voltammetry obtained Au / the morphology of the composite nanoSPAN nanomaterials , size and nature of the characterization and comparative studies . Carried out a detailed study of the four methods optimized three-step electrodeposition method , various deposition conditions the obtained Au micro / nanostructure morphology and nature of the impact , and described its possible nucleation and growth mechanism . Take advantage of this Au / nanoSPAN modified electrode constructed DNA electrochemical biosensor transgenic cauliflower mosaic virus gene fragments were detected .
