Hybrid suture coating for dual-staged control over antibacterial actions to match well wound healing progression.

Absorbable sutures have moved to the forefront in surgical fields with a huge market. Antibacterial activity is one indispensable feature for the next generation of absorbable sutures. This study develops a simple and cost-effective coating method to endow sutures with staged control over antibacterial actions to achieve enhanced dual stages of the wound healing process.

Structural Transformation in Metal-Organic Frameworks for Reversible Binding of Oxygen.

Polycyclic aromatic derivatives can trap O to form endoperoxides (EPOs) for O storage and as sources of reactive oxygen species. However, these materials suffer from structural amorphism, which limit both practical applications and fundamental studies on their structural optimization for O capture and release. Metal-organic frameworks (MOFs) offer advantages in O binding, such as clear structure-performance relationships and precise controllability.
