Review: Multimodal bioactive material approaches for wound healing

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Tissue Engineering

Background:

• Wound healing is a complex biological process involving cells, cytokines, enzymes, and growth factors.
• Dysregulation of wound healing can result in non-healing chronic ulcers.
• Existing treatments, like collagen dressings, are insufficient for the wound environment.

Purpose of the Study:

• To review current biomaterial and small molecule-based approaches for targeted wound therapy.
• To examine wound healing models used for testing material efficacy.

Main Methods:

• Literature review of biomaterial and small molecule-based wound healing strategies.
• Analysis of targeted delivery systems, including hydrogels and polymeric scaffolds.
• Evaluation of established wound healing models for material testing.

Main Results:

• Current strategies focus on delivering bioactive molecules via hydrogels or scaffolds.
• Biomaterial and small molecule-based approaches show promise for targeted wound healing.
• Various wound healing models are employed to assess material effectiveness.

Conclusions:

• A multifaceted bioactive dressing is needed to address the complexities of chronic wound healing.
• Further research into novel biomaterials and targeted delivery systems is essential.
• Standardized wound healing models are critical for evaluating therapeutic efficacy.
