Recent advances in novel materials and techniques for developing transparent wound dressings

Abstract

Optically transparent wound dressings offer a range of potential applications in the biomedical field, as they allow for the monitoring of wound healing progress without having to replace the dressing....

A Transparent, Tough and Self-Healable Biopolymeric Composites Hydrogel for Open Wound Management

“…2 Hydrogel-based dressings are increasingly popular for wound dressing applications due to their favorable characteristics, including their ability to attract water, compatibility with living tissue, shape memory with recovery, and 3D porous structure that resembles the extracellular matrix. 3 Nevertheless, hydrogels produced using a single component typically display less mechanical strength and stability. In the realm of biomedical applications, there is an urgent requirement for a technique that can confer hydrogels with both robust mechanical strength and significant biological functionalities.…”

“…Transparent wound dressings provide the advantage of monitoring wound healing progress without the need for frequent dressing replacement. 3 The cross-linking processes can be introduced into the production of the hydrogel networks. Both hydrophilic and hydrophobic polymers have been utilized to establish hydrogels through physical or chemical cross-linking.…”

“…Wound dressings offer a protective barrier against bacterial infections and also act as a guide to stimulate the reorganization of skin cells . Hydrogel-based dressings are increasingly popular for wound dressing applications due to their favorable characteristics, including their ability to attract water, compatibility with living tissue, shape memory with recovery, and 3D porous structure that resembles the extracellular matrix . Nevertheless, hydrogels produced using a single component typically display less mechanical strength and stability.…”

“…The cross-linking processes can be introduced into the production of the hydrogel networks. Both hydrophilic and hydrophobic polymers have been utilized to establish hydrogels through physical or chemical cross-linking. , The chemical cross-linking synthesis process includes co/graft-polymerization, photo reaction, enzymatic reaction, and radiation . The development of hydrogels with chemical cross-linking generally demands a reaction environment and cross-linking agents.…”

“…To be considered an ideal wound dressing, specific criteria should be met such as promoting good tissue biocompatibility, maintaining adequate mechanical stability, absorbing exudate and improving the healing process, and keeping the wound moist. Transparent wound dressings provide the advantage of monitoring wound healing progress without the need for frequent dressing replacement …”
