(a) Scheme of the OR gate. (b) Gel electrophoresis analysis. Lane 1: TL attached by Au-B (TL-B, original state sample). Lane 2: sample after adding bst to lane 1. Lane 3: sample after adding bAu to lane 1. Lane 4: sample after simultaneously adding bst and bAu to lane 1. (c) Distribution histograms of OR gate: grass green bars indicate TL-B; bottle green bars indicate TL resulting from the addition of bst; orange bars indicate TL caused by the addition of bAu; gray bars indicate TL; solid lines represent curve fitting. (d) TEM images of various output structures.
