在这项工作中,纳米粒子聚集体被用来建立一个纳米粒子计算系统,并通过添加特定的DNA信号来触发计算过程。通过DNA链置换,实现聚集的级联调节。“或”和“或与”的逻辑运算是通过DNA自组装引起的聚集而产生的颜色变化来实现的。所有反应均在室温下进行,且不改变缓冲液中的离子强度。通过对颜色的分析,计算结果可以用肉眼检测。此外,通过透射电子显微镜,清晰地显示了聚集体结构。
In this work, nanoparticle aggregation is utilized to establish a nanoparticle computing system, and the computing process is triggered by adding specific DNA signals. Through DNA strand displacement, cascading regulations of aggregations are implemented. The logic computing operations of “OR” and “OR-AND” are realized by a color change, resulting from the aggregations induced by DNA self-assembly. All reactions are performed under room temperature and without changing ion strength in buffers. By analysis of the color, the computing results can be detected through naked eyes. In addition, the aggregation structures are distinctly demonstrated by transmission electron microscopy.
