Photonic wires were constructed by sequentially arranging up to 7 fluorophores along a concatenated DNA scaffold. This yielded nanostructures displaying from one- to six-energy transfer steps where end-to-end efficiency reflected the multiple underlying photophysical processes and the ability of long-range interactions to compensate for localized non-ideal dye behaviour.
通过沿着串联的DNA支架依次排列多达7个荧光团构建了光子线。这产生了展示从一到六个能量转移步骤的纳米结构，其中端到端效率反映了多个潜在的光物理过程以及长程相互作用补偿局部非理想染料行为的能力。
