Abstract
A bio-catalytic Janus motor based on the mesoporous silica cluster (JMSC) is fabricated. Chemically conjugated catalase triggers the decomposition of H2O2 to produce driving force by bubble propulsion, while a metallic (Ni) coating layer allows for magnetic guidance of the motor. The JMSC motor can act as a delivery vehicle with cargo loading inside its mesopores.
摘要
制备了一种基于介孔二氧化硅簇（JMSC）的生物催化Janus电机。化学共轭的过氧化氢酶通过气泡推进触发过氧化氢分解以产生驱动力，而金属（镍）涂层允许对电机进行磁引导。JMSC电机可作为一种输送载体，在其介孔内装载货物。
