ABSTRACT: Hydrogel, a polymer material with a three-dimensional structure, has considerably expanded in research across multiple fields lately. However, the lack of a comprehensive review integrating the research status of hydrogel across diverse fields has hindered the development of hydrogel. This bibliometric analysis reviewed the hydrogel-related research over the past decades, emphasizing the evolution, status, and future directions within a multitude of fields, such as materials science, chemistry, polymer science, engineering, physics, biochemistry molecular biology, pharmacology pharmacy, cell biology, biotechnology applied microbiology, etc. We encapsulated applications and the potential of hydrogel in wound healing, drug delivery, cell encapsulation, bioprinting, tissue engineering, electr
