Biobased Materials In Wound Dressings

Abstract

Chronic wounds are often associated with life-threatening infections. Therefore, there is a requirement for wound-healing materials that provide an optimum environment for wound healing and are preferably biodegradable and nontoxic, thereby facilitating the wound-healing process. There is an increase in the usage of biobased wound dressings for a multitude of reasons: availability, low cost, desirable mechanical properties, amenability to chemical modifications, inherent antimicrobial activity, and structural versatility. Sodium alginate, chitosan, and cellulose are the key polymers used for the fabrication of wound dressings. Here, we have outlined the basic properties and recent advances in using them for wound dressing. © 2023 Elsevier Inc. All rights reserved.
