Fig. 3From: Flexible nanopillar-based immunoelectrochemical biosensor for noninvasive detection of Amyloid betaa Cyclic voltammogram of nanopillar electrode. The scan rate ranging from 10 to 50 mV/s was tested. b Redox peak current from the test result (a). c Reproducibility test of NPA at the scan rates of 10 and 50 mV/s with 30 cycles of repetition, with data from every fifth cycle presented. d Stability test of NPA under conditions with bending and twistingBack to article page
