DNA is a promising material for use in nanotechnology; the persistence length of double stranded DNA gives it a rigid structure in the several nanometer regime and its four letter alphabet enables addressability. We present the construction of a self-assembled DNA-based photonic wire capable of transporting excitation energy over a distance of more than 20 nm. Our results show that it is possible to create two component DNA-based photonic wires capable of long range energy transfer using a straightforward self-assembly approach.
脱氧核糖核酸（DNA）是一种很有前景的用于纳米技术的材料；双链DNA的持久长度使其在几纳米的尺度范围内具有刚性结构，并且其四个字母的编码方式实现了可寻址性。我们展示了一种基于DNA的自组装光子线的构建，该光子线能够在超过20纳米的距离上传输激发能量。我们的结果表明，使用直接的自组装方法创建能够进行长程能量转移的双组分基于DNA的光子线是可能的。
