在这项工作中,利用DNA链置换反应构建了两个DNA纳米器件。在金纳米粒子(AuNPs)和金纳米棒(AuNRs)的辅助下,纳米粒子的聚集状态可以反映出自主反应。通过序列设计,利用AuNPs和AuNRs的两个不重叠的双峰状紫外可见光谱峰,成功地实现了两个多输入多输出逻辑门的设计。该方法不仅展示了如何实现多逻辑运算,而且在多目标检测方面具有很大的潜力。
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.
