Tough bioadhesion has important implications in engineering and medicine but remains challenging to form control. We report an ultrasound (US)-mediated strategy achieve tough with controllability fatigue resistance. Without chemical reaction, the US can amplify adhesion energy interfacial threshold between hydrogels porcine skin by up 100 10 times. Combined experiments theoretical modeling suggest that key mechanism is US-induced cavitation, which propels immobilizes anchoring primers into...
Non-compressible hemorrhage is an unmet clinical challenge that accounts for high mortality in trauma. Rapid pressurized blood flows under impair the function and integrity of hemostatic agents adhesion bioadhesive sealants.

Abstract Emerging soft ionotronics better match the human body mechanically and electrically compared to conventional rigid electronics. They hold great potential for human‐machine interfaces, wearable implantable devices, machines. Among various ionotronic ionic junctions play critical roles in rectifying currents as electrical p–n junctions. Existing junctions, however, are limited mechanical performance, difficult fabricate degrade. Herein, design, fabrication, characterization of tough...
Hydrogel adhesion that can be easily modulated in magnitude, space, and time is desirable many emerging applications ranging from tissue engineering soft robotics to wearable devices. In synthetic materials, these complex behaviors are often achieved individually with mechanisms apparatus difficult integrate. Here, we report a universal strategy embody multifaceted programmability hydrogels. By designing the surface network topology of hydrogel, supramolecular linkages result contrasting...
Abstract Surgical sutures are gold‐standard wound closure devices. However, they unable to form a tight seal with surrounding tissues, raising the risks of body fluid leakage and surgical site infection. Additionally, use can result in cracking at suture roots, damage micro‐trauma soft tissues due slicing compression fibers after their placement. Bioadhesives capable mimicking natural biological interfaces appealing alternatives, but cannot achieve same level strength as conventional...
Tough adhesive hydrogels find broad applications in engineering and medicine. Such feature high resistance against both cohesion adhesion failure. The superior fracture properties may, however, deteriorate when the swell upon exposure of water. underlying correlation between polymer fraction tough remains largely unexplored. Here, we study how energies a hydrogel evolve with swelling process. results show similar scaling law (ϕv) two quantities as function (ϕ). Our analysis computational...
<title>Abstract</title> Blood clots play a pivotal role for hemostasis and regeneration1, but are slow to form mechanically weak. These limitations attributed complex coagulation cascades, high content of ineffective cells, low structural polymers2. They pose considerable risk life-threatening hemorrhage constrain the broader application blood clots3-5. Overcoming these is critical challenge, as existing strategies focused on polymer networks inapplicable highly cellularized materials like...
Abstract Hydrogels are often synthesized with thermal or photo‐initiated gelation, leaving alternative energy sources less explored. While ultrasound has been used for polymer synthesis and mechanochemistry, its application through cavitation hydrogel as a constructive force is rare, the underlying sonochemical mechanisms poorly understood.
