(a) The calibration curves of the N-OMC/PVA/Lac/Au electrode (A) and OMC/PVA/Lac/Au electrode (B) at 0.45 V (vs SCE). Inset: Amperometric responses of the N-OMC/PVA/Lac/Au electrode (A) and OMC/PVA/Lac/Au electrode (B) on successive additions obtained upon the successive addition of 0.5 mM catechol to stirred blank pH 5.0 PBS at 0.45 V (vs SCE). (b) The Lineweaver-Burk curves of the N-OMC/PVA/Lac/Au electrode (A) and OMC/PVA/Lac/Au electrode (B) at 0.45 V (vs SCE).
