Electrochemical Synthesis of Poly(3,4-ethylenedioxythiophene) and Gold Nanocomposite and Its Application for Hypochlorite Sensor
The AuNPs/PEDOT nanocomposite consisting of poly(3,4-ethylendioxythiophene) and Au nanoparticles (AuNPs) can be easily synthesized on electrode surface. It was studied to develop a new NaClO sensor with improved performance with respect to bare electrode and to pure metallic (AuNPs) modified electrodes. This nanocomposite can be performed by electrochemical co-deposition using ionic liquid 1-bu...
متن کاملFunctionalized conducting polymer as an enzyme-immobilizing substrate: an amperometric glutamate microbiosensor for in vivo measurements.
The functionalized conducting polymer (CP) of 5, 2':5', 2' '-terthiophene-3'-carboxylic acid on a platinum microelectrode was prepared through the electropolymerization process using cyclic voltammetry and was used as a substrate for the immobilization of enzymes. The nanoparticles of the CP were obtained at a high scan rate in the cyclic voltammetric experiment. A needle-type amperometric glut...
متن کاملVirus-poly(3,4-ethylenedioxythiophene) biocomposite films.
Virus-poly(3,4-ethylenedioxythiophene) (virus-PEDOT) biocomposite films are prepared by electropolymerizing 3,4-ethylenedioxythiophene (EDOT) in aqueous electrolytes containing 12 mM LiClO(4) and the bacteriophage M13. The concentration of virus in these solutions, [virus](soln), is varied from 3 to 15 nM. A quartz crystal microbalance is used to directly measure the total mass of the biocompos...
متن کاملSpectroelectrochemistry of poly(ethylenedithiathiophene)--the sulfur analogue of poly(ethylenedioxythiophene).
Poly(3,4-ethylenedithiathiophene) (PEDTT) is a polythiophene-like conjugated polymer in which each thiophene ring is functionalized with an ethylenedithia bridge. As such, PEDTT is the sulfur analogue of the well-known poly(3,4-ethylenedioxythiophene) (PEDOT). Substituent effects, namely the presence of sulfur atoms in PEDTT replacing the oxygen atoms of PEDOT, do not provide a simple explanati...
متن کاملAmperometric Enzyme Electrodes
Neste trabalho de revisão são analisados os avanços mais recentes em eletrodos enzimáticos amperométricos dando ênfase particular aos biosensores baseados na Glucose Oxidase e na Horseradish Peroxidase. A intermediação redox através de mediadores artificiais solúveis ou ligados a polímeros é discutida em termos dos desenvolvimentos teóricos recentes e verificações experimentais. É analisada a d...
