ABSTRACT
Wound dressings can be applied over the wound sites to provide long-lasting wound management and improve wound healing. Biological wound dressings are superior to synthetic materials due to biodegradability and biocompatibility. These biomaterials have demonstrated huge potential in the field of wound dressings. Applying bibliometric analysis combined with results-based descriptions to characterize the research status, hotspots, and cutting-edge topics, this study is the first in-depth qualitative, quantitative, data-driven overview of biological wound dressings research in recent decades. Filtered data were used to construct co-citation, heatmaps, bi-clustering, strategy maps, and other analyses and visualization. The results show that research on biological wound dressings has progressed considerably in the last 5 years with extensive global collaboration. A clear knowledge base has been developed. Chitosan hydrogels, bacterial cellulose, active agents (silver nanoparticles, growth factors, curcumin, etc.), and electrospinning fibers stand out as research hotspots. The research frontiers include novel starting materials, precise and controlled release systems, and clinical and regenerative medicine applications. We interpreted an overview of the excavated topics and expected the findings here to provide a guide and inspire innovations for developing the next generation wound dressings.
