Magnetically-actuated functional gradient nanocomposites can be locally modulated to generate unprecedented mechanical gradients applied to various interfaces and surfaces following the design principles of natural biological materials. Several thus-far-inaccessible biomimics including a strong and ultra-durable interface mimicking the tooth dentin–enamel junction, a wear-resistant and long-lasting surface coating mimicking biological skins, and flexible yet structurally-stable micropillars mimicking the adhesive setae of insects are demonstrated.

磁力驱动的功能梯度纳米复合材料，可实现坚固和超耐用的仿生界面/表面†

可以根据天然生物材料的设计原理，对磁驱动的功能梯度纳米复合材料进行局部调制，以生成前所未有的机械梯度，并将其应用于各种界面和表面。几种迄今无法获得的仿生生物，包括模仿牙齿牙本质-牙釉质连接的牢固且超耐用的界面，模仿生物皮肤的耐磨且持久的表面涂层，以及模仿昆虫黏附性刚毛的灵活而结构稳定的微柱被证明。
