Polymeric Materials in Biomedical Engineering: A Bibliometric Mapping

This study offers an integrated synthesis of polymeric materials in biomedical engineering, revealing four major and interlinked research domains: tissue engineering and regenerative medicine, drug delivery and nanomedicine, wound healing and antimicrobial applications, and advanced fabrication through 3D/4D printing and bioprinting. Across these areas, hydrogels, biodegradable composites, and stimuli-responsive polymers emerge as the most influential material classes. The analysis highlights substantial progress in extracellular matrix-mimetic scaffolds, smart drug delivery systems with controlled release, multifunctional wound dressings integrating antimicrobial and healing functions, and patient-specific constructs produced via additive manufacturing. Despite these advances, recurring challenges persist in long-term biocompatibility and safety, scalable and reproducible fabrication, and regulatory standardisation. The results point toward a convergence of bioactivity, manufacturability, and clinical translation, with hybrid natural-synthetic systems and personalised polymeric designs defining the next phase of biomedical polymer innovation.
