自组装是生物系统中的一个重要过程，也是实现动态和响应性微米和纳米技术的一个有前途的途径。本研究讨论了固有磁性细菌垂直于固体表面的非平衡自组装。流体动力学和磁相互作用之间的相互作用导致稳定的三维集群在长时间的制度，它可以编程组装，拆卸，并在整个表面上平移。一般的非平衡自组装的合理设计的研究结果的影响进行了讨论。
Self-assembly is an important process in biological systems and also a promising avenue toward dynamic and responsive micro- and nano-technologies. This study discusses the non-equilibrium self-assembly of inherently magnetic bacteria oriented perpendicular to a solid surface. An interplay between hydrodynamic and magnetic interactions leads to stable three-dimensional clusters in the long-time regime, which may be programmatically assembled, disassembled, and translated across a surface. The implications of the findings for the rational design of non-equilibrium self-assembly in general are discussed.
