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。
New nanoelectronic devices require accurate and controlled spatial alignment of optical components at the nanometer scale. DNA has a unique base-pairing recognition mechanism and double-helix structure, as well as the preparation of simple, shape and size can be programmed design, and can be precisely fixed-point modification and other advantages, it has been used as a template assembly of various types of supramolecules are widely used in nano-optoelectronics and Nano-medicine and other fields. The DNA assembly photon array is a series of chromogenic functional groups according to the design needs of precise positioning on the DNA template, through the multi-step fluorescence resonance energy transfer, the completion of the photon transfer process. In this paper, the recent advances in photonic arrays based on DNA assembly are summarized, and the prospects for future developments are also reviewed.
