- W1990573409 abstract "Abstract The polypyrrole microfibres were synthesized potentiodynamically on platinum electrodes using the natural surfactant Quillaja Saponin . Employing amperometric and impedimetric techniques, the suitability of these electrodes as biosensors for catechol is investigated, in the presence of the enzyme Tyrosinase . The amperometric measurements reveal the linear concentration regime from 1 μM to 400 μM while the upper limit of detection using impedance studies is estimated as 200 μM. The fitting of the Nyquist and Bode’ plots is carried to deduce the system parameters. The low magnitude of Michaelis–Menten constant (103 μM) suggests the high activity of the Tyrosinase enzyme. The temporal stability of the electrode has been estimated and the effect of interference from phenol, resorcinol and ascorbic acid is also investigated." @default.
