(a) Scheme of AND gate. (b) Gel electrophoresis analysis. Lane 1: TL attached by Au-A and Au-B (TL-AB, original state sample). Lane 2: sample after adding A to lane 1. Lane 3: sample after adding B to lane 1. Lane 4: sample after simultaneously adding A and B to lane 1. (c) Distribution histograms of AND gate: purple bars indicate TL-AB; blue bars indicate TL-B caused by the displacement of Au-A from TL-AB; pink bars indicate TL-A caused by the displacement of Au-B from TL-AB; gray bars indicate TL; solid lines represent curve fitting. (d) TEM images of various output structures.
