Figure 7From: A disposable biosensor based on immobilization of laccase with silica spheres on the MWCNTs-doped screen-printed electrodeThe selective determination of DA in the coexistence of AA. The solid curve stands for DPV obtained in 0.10 M PBS (pH 5.0) containing 85.5 μM DA. The dash curves 1, 2 and 3 represent DPVs obtained after introducing 20.0 μM (curve 1), 40.0 μM (curve 2) and 60.0 μM (curve 3) AA, respectively.Back to article page
