(A) The grafting ratio of different weights of Aβab reacted with 1 mg MNG. (B) The change in current by different volumes of Aβab-MNG dropped onto Au electrode. (C) The change in current by various incubation times of Aβab-MNG modified Au electrode with 800 pg mL−1 Aβ42. Error bars represent the standard deviation (SD) from three independent determinations.
