We describe the self-assembly of a DNA crystal that contains two tensegrity triangle molecules per asymmetric unit. We have used X-ray crystallography to determine its crystal structure. In addition, we have demonstrated control over the colors of the crystals by attaching either Cy3 dye (pink) or Cy5 dye (blue-green) to the components of the crystal, yielding crystals of corresponding colors. Attaching the pair of dyes to the pair of molecules yields a purple crystal.
我们描述了一种 DNA 晶体的自组装,该晶体每个不对称单位包含两个张拉整体三角形分子。我们使用 X 射线晶体学确定了其晶体结构。此外,我们通过将 Cy3 染料(粉色)或 Cy5 染料(蓝绿色)连接到晶体的组成部分上,从而控制晶体的颜色,展示了对晶体颜色的控制,得到了相应颜色的晶体。将这对染料连接到这对分子上得到一个紫色晶体。
