Engineered catechol-based composite materials for diabetic wound healing

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Materials Chemistry

Background:

• Diabetic wound healing is a complex challenge often inadequately addressed by single-target therapies.
• Naturally derived catechol/polyphenolic compounds offer versatile building blocks for advanced wound repair systems.
• Existing therapies struggle to manage the multifaceted pathological network of diabetic wounds.

Purpose of the Study:

• To systematically review composite material systems utilizing catechol chemistry for diabetic wound repair.
• To establish a multi-scale materials design framework for intelligent, responsive wound healing platforms.
• To elucidate the interaction mechanisms and synergistic therapeutic effects of these materials.

Main Methods:

• Discussion of composite material systems engineered from nano- to macro-scales using catechol chemistry.
• Framework for designing nanoparticles, nanozymes, metal-phenolic networks, and macroscopic devices (hydrogels, microneedles, scaffolds).
• Analysis of interactions between multi-scale composites and biological systems, focusing on therapeutic mechanisms.

Main Results:

• Demonstration of catechol-based composites enabling systematic regulation of the diabetic wound healing process.
• Elucidation of multi-level synergistic effects including ROS scavenging, macrophage reprogramming, and enhanced neurovascular regeneration.
• Identification of structure-activity relationships crucial for intelligent material design.

Conclusions:

• Cross-scale integration and intelligent design of catechol-based composite materials are vital for effective diabetic wound repair.
• Future research should focus on biosafety, mechanistic understanding, standardized fabrication, and personalized treatments for clinical translation.
• These materials represent a promising theoretical framework and design guidance for high-efficiency diabetic wound repair solutions.
