The human body possesses a remarkable ability to repair itself through the intricate and highly coordinated process of wound healing. However, in many pathological conditions, such as diabetes, chronic inflammation, and severe burns, this natural process becomes disrupted, resulting in persistent and often life-threatening wounds. Addressing such challenges requires innovative therapeutic strategies that merge biological insight with advanced materials science. Over the last two decades, biopolymers have emerged as a transformative solution in wound management. Their biocompatibility, biodegradability, and tunable properties allow them to mimic the extracellular matrix, deliver bioactive agents, and create optimal healing environments. This book, Biopolymers for Impaired Wound Healing, brings together contributions from leading researchers and clinicians to present a holistic view of how biopolymers are revolutionizing wound care. Biopolymers are natural polymers produced by living organisms. They are essentially large molecules made up of repeating smaller units called monomers, linked together by covalent bonds. Unlike synthetic polymers, derived from fossil fuels, biopolymers are naturally derived from biological sources, such as plants, animals, and microorganisms. The book is a result of the growing urgency to address one of the most persistent challenges in modern medicine: the effective treatment of chronic and non-healing wounds. Despite remarkable advances in surgical techniques, pharmacotherapy, and regenerative medicine, impaired wound healing continues to burden patients and healthcare systems worldwide— particularly in aging populations and individuals with diabetes, vascular disorders, or immune dysfunction. This book explores the transformative potential of biopolymers—naturally derived or bioengineered macromolecules—as innovative tools in wound care. Biopolymers offer unique advantages: biocompatibility, biodegradability, tunable mechanical properties, and the ability to deliver therapeutic agents directly to the wound site. From chitosan and alginate to collagen and hyaluronic acid, these materials are redefining how we approach tissue repair, inflammation control, and cellular regeneration. The chapters provide a multidisciplinary perspective, integrating insights from biomaterials science, molecular biology, clinical medicine, and bioengineering. We examine the mechanisms by which biopolymers interact with the wound microenvironment, their role in modulating immune responses, and their application in advanced wound dressings, scaffolds, and drug delivery systems. The book is intended for researchers, clinicians, biomedical engineers, and students who seek to deepen their understanding of wound pathophysiology and explore cutting-edge solutions rooted in biopolymer science. The book will not only inform but also inspire further innovation, bridging the gap between laboratory discovery and bedside application. The chapters span from fundamental biology to clinical application. Chapter 1 is an in-depth discussion on the biological stages of healing and how they guide the design of next-generation therapies. Chapter 2 explores how specific properties of biopolymers align with wound healing mechanisms to accelerate repair. Chapter 3 focuses on strategies to overcome the impaired healing environment of diabetic wounds, while Chapter 4 reviews advancements in reducing scarring, preventing infection, and regenerating skin in burn patients. Chapter 5 highlights chitosan’s antimicrobial and regenerative properties for stubborn wounds, and Chapter 6 describes alginate’s gel-forming and controlled release abilities in wound dressings. Chapter 7 examines hyaluronic acid’s hydrating and signaling roles in tissue repair, while Chapter 8 discusses cellulose-based dressing innovations for chronic and non-healing wounds. Chapter 9 explains dextran’s role in mimicking the extracellular matrix and aiding repair and Chapter 10 presents collagen’s structural benefits and its integration into novel delivery systems. Chapter 11 describes strategies to combine antimicrobials with biopolymers for infection control, and Chapter 12 highlights these polysaccharides’ biodegradability, moisture retention, and healing potential. Chapter 13 gives descriptions of the clinical application of cellulose and Chapter 14 highlights clinical trials in burn wounds. The book combines mechanistic insights with practical applications, bridging the gap between laboratory research and clinical practice. It provides the scientific community and healthcare professionals with a comprehensive reference to the latest developments in biopolymer-based wound healing.
