Self-assembly of symmetric finite-size DNA nanoarrays.
We report a novel and cost-effective strategy to self-assemble finite-size DNA nanoarrays. This strategy takes advantage of the geometric symmetry of the DNA nanostructures. In general, to construct a 2D array with a total of N tiles containing Cm symmetry, where m = 2, 3, 4, or 6, the number of unique tiles the fixed-size array requires is N/m, if N/m is an integral number, or Int(N/m) + 1, if N/m is an nonintegral number. We herein demonstrate two examples of fixed-size arrays with C2 and C4-fold symmetry.dagger
