Abstract
We demonstrate a simple physical fabrication method to control surface roughness of Janus micromotors and fabricate self-propelled active Janus microparticles with rough catalytic platinum surfaces that show a four-fold increase in their propulsion speed compared to conventional Janus particles coated with a smooth Pt layer.
摘要
我们展示了一种简单的物理制造方法，用于控制Janus微电机的表面粗糙度，并制造出具有粗糙催化铂表面的自驱动活性Janus微粒，与涂有光滑铂层的传统Janus微粒相比，其推进速度提高了四倍。
