Research Progress on Extracellular Matrix-Based Composite Materials in Antibacterial Field.

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Infectious Disease Research

Background:

• Extracellular matrix (ECM) materials are recognized for excellent biocompatibility, biodegradability, and tissue regeneration capabilities.
• ECM materials possess inherent antimicrobial properties through the release of antimicrobial peptides (AMPs) during degradation.
• These properties make ECM materials highly attractive for applications in tissue healing and combating infections.

Purpose of the Study:

• To review recent advancements in antibacterial extracellular matrix (ECM) materials.
• To discuss the antibacterial mechanisms and functions of both free-standing and composite ECM materials.
• To identify challenges and future prospects for ECM materials in the anti-infection field.

Main Methods:

• Exploration of physical and chemical strategies to integrate antibacterial agents with ECM materials.
• Leveraging ECM properties like porous adsorption, hydrophilic adsorption, and crosslinking (group and electrostatic) for enhanced efficacy.
• Review of existing literature on ECM-based antibacterial materials and their performance.

Main Results:

• ECM materials demonstrate a dual function: promoting tissue regeneration and exerting potent antibacterial effects via AMP release.
• Various integration methods enhance the antibacterial efficacy of ECM materials.
• Both intrinsic ECM properties and composite strategies contribute to antibacterial activity.

Conclusions:

• ECM-based antibacterial materials offer a promising strategy for simultaneous tissue regeneration and infection control.
• Further research into challenges and future prospects is crucial for advancing ECM materials in clinical anti-infection applications.
• Optimizing integration techniques and understanding mechanisms will drive innovation in this field.
