A theoretical model which takes into account the structural distortion of double-crossover DNA tiles has been studied to investigate its effect on lattice formation sizes. It has been found that a single vector appropriately describes the curvature of the tiles, of which a higher magnitude hinders lattice growth. In conjunction with these calculations, normal mode analysis reveals that tiles with relative higher frequencies have an analogous effect. All the theoretical results are shown to be in good agreement with experimental data.
研究了一个考虑双交叉 DNA 瓦片结构扭曲的理论模型，以研究其对晶格形成尺寸的影响。结果发现，一个单一的向量可以很好地描述瓦片的曲率，而较大的曲率会阻碍晶格的生长。结合这些计算，简正模分析表明，相对较高频率的瓦片具有类似的效果。所有的理论结果都与实验数据吻合得很好。
