FLORINA TEODORESCU, CECILIA LETE, MARIANA MARIN, CORNEL MUNTEANU, NICOLAE TOTIR A NOVEL GLUCOSE BIOSENSOR BASED ON POLY(AZULENE-CO-3-THIOPHENE ACETIC ACID) CONDUCTING FILMS
Catalytic properties of poly(azulene-co-3-thiophene acetic acid) films were tested as mediator-carrying enzyme for glucose detection. Poly(azulene-co-3-thiophene acetic acid) films were characterized using Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS) and Scanning Electron Microscopy (SEM) methods. The cross-linking method for glucose oxidase (Gox) immobilization on the electrode surface was employed. The calibration curves for glucose amperometric detection were obtained in the range between 40-200mM. The detection limit was 27.65 mM.
