In this work, two DNA nanodevices were constructed utilizing a DNA strand displacement reaction. With the assistance of gold nanoparticles (AuNPs) and gold nanorods (AuNRs), the autonomous reactions can be reflected from the aggregation states of nanoparticles. By sequence design and the two non-overlapping double hump-like UV-vis spectral peaks of AuNPs and AuNRs, two logic gates with multiple inputs and outputs were successfully run with expected outcomes. This method not only shows how to achieve computing with multiple logic calculations but also has great potential for multiple targets detection.
在这项工作中，利用DNA链置换反应构建了两种DNA纳米器件。在金纳米颗粒（AuNPs）和金纳米棒（AuNRs）的辅助下，可以从纳米颗粒的聚集状态反映出自发反应。通过序列设计以及AuNPs和AuNRs的两个不重叠的双峰状紫外-可见光谱峰，成功运行了两个具有多个输入和输出的逻辑门，并得到了预期结果。该方法不仅展示了如何通过多种逻辑计算实现运算，而且在多目标检测方面具有巨大潜力。
