The 1D DNA template and the derivative 1D gold NP array. (a) The pathway of 1D gold NP array from the 1D DNA template. The yellow dots denote streptavidin labeled NPs, which were able to be anchored at the center of each 4×4 tile by the binding between biotin and streptavidin. (b), (c) The TEM image of the 1D gold NP array. The scale bars in both (b) and (c) are 20 nm.
