Abstract (original English)

Wound healing is a complex, multifaceted biological process that plays a vital role in recovery and overall quality of life. However, conventional wound care methods often prove insufficient, resulting in delayed healing, higher infection risk, and other complications. In response, biomaterials-especially hydrogels-have gained attention for their advanced wound management capabilities, which support wound healing by maintaining moisture, mimicking the extracellular matrix (ECM), and enabling targeted drug delivery triggered by wound-specific signals. They frequently carry antimicrobial or anti-inflammatory agents, promote blood vessel and nerve regeneration, and are biocompatible with customizable properties suited to different healing stages. Natural hydrogels, derived from polysaccharides, proteins, and peptides, offer several advantages over synthetic options, including inherent bioactivity, enzymatic degradability, and cell-adhesive qualities that closely resemble the native ECM. These features facilitate cell interaction, modulate inflammation, and speed up tissue remodeling. Moreover, natural hydrogels can be engineered as delivery systems for therapeutic agents like antimicrobial compounds, nanoparticles, growth factors, and exosomes. This review discusses recent advances in the use of natural hydrogels as multifunctional wound dressings and delivery platforms, with a fo
