Inspired by biological chemotaxis along circular paths, we propose a hydrodynamic molecular scale hunter that can swim and can find its target. The system is essentially a stochastic low-Reynolds-number swimmer with the ability to move in two-dimensional space and to sense the local value of the chemical concentration emitted by a target. We show that, by adjusting the geometrical and dynamical variables of the swimmer, we can always achieve a swimmer that can navigate and can search for the region with a higher concentration of a chemical emitted by a source.
受沿圆形路径的生物趋化作用启发，我们提出了一种流体动力学分子尺度的猎手，它既能游动又能找到目标。该系统本质上是一个随机低雷诺数游动体，能够在二维空间中移动并感知目标发出的化学物质浓度的局部值。我们表明，通过调整游动体的几何和动力学变量，总能实现一个能够导航并搜索源发出的化学物质浓度较高区域的游动体。
