Multi-agent systems demonstrate the ability to collectively perform complex tasks (e.g., construction, search, and locomotion) with greater speed, efficiency, or effectiveness than could a single agent alone. Direct and indirect coordination methods allow agents to collaborate to share information and adapt their activity to fit dynamic situations. A well-studied example is quorum sensing (QS), a mechanism allowing bacterial communities to coordinate and optimize various phenotypes in response to population density. Here we implement, for the first time, bio-inspired QS in robots fabricated from DNA origami, which communicate by transmitting and receiving diffusing signals. The mechanism we describe includes features such as programmable response thresholds and quorum quenching, and is capable of being triggered by proximity of a specific target cell. Nanoscale robots with swarm intelligence could carry out tasks that have been so far unachievable in diverse fields such as industry, manufacturing, and medicine.

展示群体感应的纳米级机器人

多代理系统展示了集体执行复杂任务(例如,构建、搜索和移动)的能力,其速度、效率或效果比单独的单个代理更快。直接和间接协调方法允许代理协作共享信息并调整其活动以适应动态情况。一个经过充分研究的例子是群体感应 (QS),这是一种允许细菌群落协调和优化各种表型以响应人口密度的机制。在这里,我们首次在由 DNA 折纸制成的机器人中实现了仿生 QS,这些机器人通过发送和接收扩散信号进行通信。我们描述的机制包括可编程响应阈值和群体淬灭等功能,并且能够被特定目标细胞的接近触发。具有群体智能的纳米级机器人可以执行迄今为止在工业、制造和医学等不同领域无法实现的任务。
