Abstract: A system is described comprising self-propelled bodies such as bacteria or nanoparticles, which can be activated with an external field to move in a desired direction. The self-propelled bodies, or swimmers, are contained in a flexible membrane which is mechanically manipulated through the movement of the swimmers. By controlling the applied field, which can be magnetic, chemical or gravitational, the flexible membranes can be translated and/or deformed.

Abstract translation: 描述了一种系统，其包括诸如细菌或纳米颗粒的自推进体，其可以通过外部场来激活以沿期望的方向移动。 自推进的身体或游泳者被包含在通过游泳者的运动机械地操纵的柔性膜中。 通过控制施加的磁场，其可以是磁性的，化学的或重力的，柔性膜可以被平移和/或变形。

Abstract: Systems and methods for altering the geometry of a fluid channel to prevent upstream mobility of bacteria, using angled obstacles on the interior of the channel that among other things creates vortices that restrict the mobility. An optimized geometry can be realized by an artificial intelligence algorithm or similar methods based on performance of various configurations of obstacle parameters.
