Abstract

Bio-inspired surfaces are usually designed by imitating the surface properties of a particular biological species, or combing with the surface characteristics of multiple biological species to construct a cross-species surface. Herein, inspired by the structure and rhythmic swing of human pulmonary cilia, and the directional migration of pigeons by geomagnetic field, an integrated system of biomimetic hydrophobic magnetic cilia array surface with reversible deformation properties and excellent magnetic response performance for solid microspheres underwater transport is designed and constructed. Driven by an external magnetic field, the magnetic responsive cilia array surface can directionally and continuously transport microspheres underwater in periodic motion. This work will shed new light on the designing of micromanipulation systems for micro-objects transport, and promote the practical application of micro-operating systems in underwater transportation and drug delivery.

生物启发的磁响应纤毛阵列表面，用于微球水下定向运输

摘要

受生物启发的表面通常是通过模仿特定生物物种的表面特性，或与多种生物物种的表面特性结合以构建跨物种表面而设计的。在此，受人肺纤毛的结构和节律性变化以及地磁场对鸽子的定向迁移的启发，设计了具有可逆形变特性和优异磁响应性能的仿生疏水磁纤毛阵列表面集成系统，用于固体微球水下运输。并建造。在外部磁场的驱动下，磁响应纤毛阵列表面可以周期性地定向和连续地在水下传输微球。
