100微米大小的自推进（活性）粒子可以被认为是表征更复杂的生物有机体（如游动细菌或运动细胞）的模型系统。我们用软光刻技术制作了非对称的微泳者，并研究了它们在衬底上和通道边界附近的圆周运动。我们的实验观察是完全符合布朗动力学理论的不对称自推进粒子，耦合他们的平移和定向运动。
Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We produce asymmetric microswimmers by soft lithography and study their circular motion on a substrate and near channel boundaries. Our experimental observations are in full agreement with a theory of Brownian dynamics for asymmetric self-propelled particles, which couples their translational and orientational motion.
