Advances in Fibrin-Based Materials in Wound Repair: A Review

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Materials Science

Background:

• Hemostasis involves platelet aggregation and the coagulation cascade, forming a blood clot that stops bleeding.
• Fibrin fibers within the clot serve as a provisional matrix, scaffolding tissue regeneration and cell migration.
• Fibrin modulates healing, provides antimicrobial defense, and sequesters growth factors.

Purpose of the Study:

• To review recent advances in fibrin and fibrin-fiber-based materials for wound healing and tissue repair.
• To discuss the mechanisms of fibrin-based materials in wound healing stages.
• To highlight modifications of fibrin with advanced materials for improved stability and efficacy.

Main Methods:

• Review of current literature on fibrin-based biomedical materials.
• Analysis of fibrin's role in wound healing processes.
• Discussion of fibrin modification strategies and composite material properties.

Main Results:

• Fibrin-based materials function as physical barriers, entrap bacteria, and facilitate drug/cell delivery.
• Pure fibrin lacks mechanical strength for standalone wound repair.
• Fibrin modification with advanced materials enhances stability and medical efficacy.

Conclusions:

• Fibrin-based nanocomposites show promise in wound repair, drug delivery, and skin reconstruction.
• Drug-loaded fibrin materials offer advanced biomedical applications.
• Further research into mechanical properties of fibrin composites is crucial for clinical translation.
