Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Drug Delivery Systems

Background:

• Chronic wounds represent a significant clinical challenge demanding innovative therapeutic approaches.
• Conventional hydrogels, while biocompatible, lack the adaptability required for complex wound microenvironments.
• The dynamic nature of chronic wounds, characterized by pH changes, oxidative stress, and enzymatic activity, necessitates advanced treatment strategies.

Purpose of the Study:

• To review the synthesis, principles, and design of smart responsive hydrogels for chronic wound healing.
• To explore the applications of these advanced hydrogels in modulating drug release and eliminating pathological factors.
• To discuss future directions and potential of smart hydrogels in enhancing wound regeneration.

Main Methods:

• Review of literature on smart responsive hydrogel synthesis and characterization.
• Analysis of hydrogel responses to various stimuli (pH, enzymes, light, electricity).
• Evaluation of hydrogel applications in promoting antibacterial effects, angiogenesis, and cell proliferation.

Main Results:

• Smart responsive hydrogels can dynamically alter properties in response to specific wound stimuli.
• Stimuli-responsive hydrogels enable controlled modulation of drug release and targeted elimination of harmful factors.
• These hydrogels facilitate key biological processes essential for effective wound healing, including antimicrobial action and tissue repair.

Conclusions:

• Smart responsive hydrogels represent a promising platform for advanced chronic wound management.
• Their ability to sense and respond to the wound microenvironment offers superior therapeutic potential compared to conventional hydrogels.
• Further development holds significant promise for improving patient outcomes in chronic wound care.
