论文摘要
通常需要增强活性纳米或显微镜游泳者的运动能力，例如，自propell的Janus颗粒作为化学反应的药物或弱精子细胞的剂，以更好地获得成功的受精机会。在这里，我们基于这样的想法解决了这个问题，即运动可以从更活跃的来宾物种转移到活跃的宿主物种。我们在两种典型情况下进行了运动转移的数值模拟，即通过研究其速度分布，并通过研究其积液率来分析其速度分布和相互作用过度阻尼的颗粒来进行弱惯性效应的相互作用。在这两种情况下，我们都以高达四倍的宿主物种的运动来检测运动性转移。这种运动性增强技术可以在化学，生物学和医学中找到应用。
It is often desirable to enhance the motility of active nano- or microscale swimmers such as, e.g., self-propelled Janus particles as agents of chemical reactions or weak sperm cells for better chances of successful fertilization. Here we tackle this problem based on the idea that motility can be transferred from a more active guest species to a less active host species. We performed numerical simulations of motility transfer in two typical cases, namely for interacting particles with weak inertia effect, by analyzing their velocity distributions, and for interacting overdamped particles, by studying their effusion rate. In both cases we detected motility transfer with a motility enhancement of the host species of up to a factor of four. This technique of motility enhancement can find applications in chemistry, biology and medicine.
