Microneedles: a novel strategy for wound management

Area of Science:

• Biomedical Engineering
• Materials Science
• Regenerative Medicine

Background:

• Wound management faces challenges with traditional dressings due to poor drug absorption in complex wound environments.
• Efficient wound healing is critical, addressing significant global health and economic burdens.

Purpose of the Study:

• To review and analyze recent research on microneedle applications in wound management.
• To classify microneedle-based wound healing strategies by efficacy.
• To explore the future potential of microneedles in advanced wound care.

Main Methods:

• Systematic review and analysis of current microneedle research in wound management.
• Classification of microneedle applications based on therapeutic effects: hemostasis, antibacterial, proliferation, anti-scar, and monitoring.
• Evaluation of the current state and limitations of microneedle patches.

Main Results:

• Microneedles improve transdermal drug delivery for enhanced wound healing by overcoming local barriers.
• Research highlights microneedles' efficacy in hemostasis, antibacterial action, promoting cell proliferation, reducing scarring, and enabling wound monitoring.
• Advanced microneedle designs show potential for targeted and efficient therapeutic delivery.

Conclusions:

• Microneedles represent a promising innovation for overcoming limitations of traditional wound dressings.
• Further development of microneedle technology is crucial for creating smarter and more effective wound management strategies.
• Future research should focus on optimizing microneedle design and clinical translation for diverse wound types.
