Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout

An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Microbubble Shell Stiffness Engineering Enhances Ultrasound Imaging, Drug Delivery, and Sonoporation
Shell‐engineered poly(alkyl cyanoacrylate) microbubbles with tunable stiffness improve ultrasound imaging and therapy. Adjusting the length of the alkyl chain and the glass transition temperature maintains a narrow microbubble size distribution while enhancing drug loading, sonoporation and the acoustic response.

Hydrogels demonstrate material properties that mimic the mechanical and chemical environments of biological tissues. Yet, they face challenges during their integration into 3D interfaces. By identifying a class of thermoplastic hydrogels, a strategy is developed to pattern hydrogels in thermally drawn fibers.

Inspired by mussel proteins, YDC‐Gel‐Zn is a smart bone glue designed for osteoporotic implants. It adheres strongly to both metal implants and bone for initial fixation. In osteoporosis's inflammatory environment, it sequentially releases zinc ions and therapeutic peptides: the zinc modulates immune cells to reduce inflammation, while the peptides ...

Tailored Xenogeneic‐Free Polymer Surface Promotes Dynamic Migration of Intestinal Stem Cells
This study introduces a PoLymer‐coated Ultra‐stable Surface (PLUS), a nitrogen plasma‐treated poly(ethyleneglycoldimethacrylate), as a stable xenogeneic‐free platform for intestinal stem cell culture. PLUS enhances cell attachment, supports actin‐driven migration, and retains functionality after 3 years of storage. Promoting cytoskeletal reorganization,
