Fig. 3From: Diamine oxidase-modified screen-printed electrode for the redox-mediated determination of histaminea Representation of Δi vs. different histamine concentrations (5, 10, 25, 50, and 75 mg L−1) obtained with the developed sensor by chronoamperometry at + 0.20 V for 120 s. b) Δi for 25 mg L−1 histamine obtained with the same sensor along 35 days. Average values ± SD obtained with three different sensors are representedBack to article page
