Abstract The capacity of biological tissues to undergo self‐healing is crucial for the performance functions and continuation life. Conventional intrinsic materials demonstrate analogous functionality depending on dissociation‐recombination reversible bonds with no need extra repair agents. However, trade‐off relationship between mechanical strength kinetics in systems, coupled lack additional functionality, restricts their service life practical applications. Diversified highly ordered structures organisms significantly affect energy dissipation mechanism, signal transmission efficiency, molecular network reconstruction capability due multi‐dimensional differentiated macroscopic composite constructions, microscopic orientation textures, topologies/bonding types at level. These architectures exhibit distinctive strengthening mechanisms functionalities, which provide valuable references. This review aims providing current status advanced biomimetic internal micro/nanostructures. Through highlighting specific examples, classifications, design inspirations, fabrication strategies these newly developed based integrating dynamic interactions nano/microstructures are outlined. Furthermore, balance mechanisms, structure–functionalization relationships, potential application values discussed. concludes a perspective challenges, opportunities, prospects development, application, promotion self‐healable bio‐like architectures.
