Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Synchronizing the Osteochondral Regeneration Process through Spatial Patterning of Stable and Hypertrophic Cartilage Organoids

Advanced Materials, EarlyView.
Zonated osteochondral assembloid implants are engineered through scaffold‐free spatial assembly of induced pluripotent stem cell (iPSC)‐derived chondrocyte organoids and periosteum‐derived osteogenic organoids. Implanted into full‐thickness rat osteochondral defects, they promote hyaline‐like cartilage repair, support subchondral bone formation with ...

Sea Urchin‐Inspired Immuno‐Instructive Ionic Flow Drives MSCs‐Macrophage Communication to Promote Bone Regeneration

Advanced Materials, EarlyView.
ABSTRACT Bone tissue regeneration is a complex physiological process dependent on the spatiotemporal coordination of immune cells and stem cells. Conventional research primarily elucidates the mechanism through which materials facilitate bone formation by initially modulating macrophages and subsequently encouraging the osteogenic differentiation of ...
