Pixel-to-pixel reproducibility for DNA detection. All three sensing electrodes (S1, S2, and S3) within the array were modified with the H1N1 probe DNA. The MB reduction current from each working electrode is indicated before (solid line) and after (dashed line) hybridization with the H1N1 target. The sensors yielded a uniform signal of 59 ± 4%. The measurements were taken 25 min after injection of the target at 400 nM. All three probes were then regenerated with room-temperature DI water (dotted line) with excellent recovery and reproducibility (98 ± 2%).
