White Roman goose (Anser anser domesticus) feathers, comprised of oriented conical barbules, are coated with gland-secreted preening oils to maintain a long-term nonwetting performance for surface swimming. The geese accustomed combing their plumages flat bills in case they contaminated oleophilic substances, during which the amphiphilic saliva spread over barbules greatly impairs hydrophobicities and allows trapped contaminants be anisotropically self-cleaned by water flows. Particularly, superhydrophobic behaviors feathers recovered as well. Bioinspired switchable anisotropic self-cleaning functionality white geese, unidirectionally inclined structures engineered through integration scalable colloidal self-assembly technology lithographic approach. dependence directional sliding properties on shape, inclination angle, size is systematically investigated this research. Moreover, functionalities demonstrated Sudan blue II/water (0.01%) separation performances. feather-inspired coatings undoubtedly offer new concept developing innovative applications that require transportation collection liquids.

Abstract Infected wound healing remains a significant clinical challenge, demanding innovative therapeutic strategies to simultaneously address bacterial elimination, tissue regeneration, and controlled drug delivery. Inspired by the hierarchical structure of crocodile teeth, bioinspired, 3D‐printed microneedle patch integrating Mxene nanosheets polymerizable deep eutectic solvent (PDES) composed vinyl pyrrolidone (VP), itaconic acid (IA), N‐isopropyl acrylamide (NIPAM) is developed. The resulting MXene‐based eutectogel (MF‐MXene@MN) combines photothermal responsiveness, antioxidant activity, temperature‐triggered release for conversion reactive oxygen species (ROS) scavenging. gradient‐height design inspired teeth enhances adhesion, while DLP 3D printing enables personalized dressing geometries with <50 µm resolution. In vitro in vivo studies demonstrated 94.88% closure rate within 10 days, 3.2‐fold increased angiogenesis, 68% reduced viability ( S. aureus : 32.59%; E. coli 48.17% under NIR), pH‐/temperature‐responsive mangiferin (88.3% cumulative via 5 NIR cycles). These synergistic functions promote healing, offering superior antibacterial ability, regeneration promotion, control compared traditional dressings systems. This multifunctional platform integrates bioinspired design, stimuli‐responsive materials, additive manufacturing, providing transformative solution precision management.
