Nature Communications, Published online: 28 April 2026; doi:10.1038/s41467-026-72468-8 Existing Janus hydrogels struggle to combine high-strength, asymmetric adhesion, and simple fabrication. Here, the authors develop a high-strength Janus hydrogel with bilateral asymmetric adhesion for wet tissue hemostasis and intestinal/intrauterine anti-adhesion.
Hydrogels are chemically or physically cross-linked three-dimensional networks that are water insoluble but can absorb a large amount of water or biological fluids and maintain their semisolid morphology. Besides their various applications in superabsorbents, cosmetics and food, contact lenses, actuators and sensors in the materials science domain, hydrogels have become more and more attractive i…
