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.

Abstract Cellulose nanocrystals (CNCs) are commercially available materials derived from cellulose, the most abundant biopolymer on our planet. Due largely to their high strength, surface area‐to‐volume ratio, tailorable chemistry, and abundance of biomass feedstocks with which produce them, CNCs have attracted significant interest in applications spanning paints coatings, composites, packaging, biomedical sectors. However, perhaps interestingly, will self‐assemble (or, as I've teased title, organize ) form highly ordered chiral nematic liquid crystal phases when concentrated suspension. Upon complete solvent evaporation, this order is ‘locked’, yielding films structural colour—colour arising not due chemical pigments, but rather physical structure a material itself. In pursuit novel multi‐functional materials, research has shifted recently towards incorporation functional additives composite films. Along introducing basics crystals self‐assembly, review discusses main approaches used CNC‐based films: co‐assembly, templating, post‐processing, highlights exceptional examples each case. Finally, I give my uniquely Canadian perspective current status, future prospects, major challenges associated development materials.
