新型纳米光电器件需要在纳米尺度实现对光学元件进行精确和可控的空间排列。DNA具有独特的碱基配对识别机制和双螺旋结构，以及制备简单，形状和尺寸均可程序化设计，并可精确定点修饰等优势，因此已经作为模板组装各类超分子广泛应用于纳米光电和纳米医学等领域。DNA组装的光子阵列是将一系列的发色官能团根据设计需要精确定位在 DNA模板上，通过多步荧光共振能量转移，完成光子的传递过程。文章主要综述了近年来基于 DNA组装的光子阵列取得的新进展，并对以后的发展进行展望。%The development of nano-optoelectronic devices is especially relevant to the control of the spatial arrangement of photoactive materials with nanoscale precision. Because of its base pairing and double-helix structure, as well as easy preparation, programmable control over their shape and size, and precise spatial addressability, DNA has been used as the template to organize a variety of nanoscale elements for nanophotonics and nanomedical research. The DNA-based photonic arrays are multiple lfuorophores programmed sequentially along DNA scaffold to achieve energy transfer through multi-step lfuorescence resonance energy transfer. In this review, the discussion focused on the progrsses of DNA-based assembly photonic arrays in recent years, and insights for future directions were provided.
