报告题目：三维可形变仿生材料的构建及其用于生物活性界面（Three Dimensional Deformable Biomimetic Heterostructures for Dynamic Biointerfaces）

报告摘要：Scales are rooted in soft tissues, and are regenerated by specialized cells. Therealization of dynamic synthetic analogues with inorganic materials has been a significant challenge, because the abiological regeneration sites that could yield deterministic growthbehavior are hard to form. Here we have overcome this fundamental hurdle byconstructing a mutable and deformable array of three-dimensional calcite heterostructuresthat are partially locked in silicone. Individual calcite crystals exhibit asymmetricaldumbbell shapes and are prepared by a parallel tectonic approach under ambientconditions. The silicone matrix immobilizes the epitaxial nucleation sites through self-templated cavities, which enables symmetry breaking in reaction dynamics and scalablemanipulation of the mineral ensembles. With this new platform, we devised severalmineral-enabled dynamic surfaces and interfaces. For example, we showed that theinduced growth of minerals yielded localized inorganic adhesion for biological tissue andreversible focal encapsulation for sensitive components in flexible electronics.
