Bibliometric analysis of nanomaterials in hepatocellular carcinoma treatment: research trends, knowledge structures, and emerging insights (2000-2024).

This study analyzes the research landscape of nanomaterials in treating hepatocellular carcinoma (HCC) and examines publication trends in this field by conducting a comprehensive bibliometric analysis within the Web of Science Core Collection (WoSCC) database. Articles published from 2000 to September 16, 2024 were retrieved using a structured search formula targeting studies on nanomaterials in HCC, including nanoparticles, nanodots, nanorods, nanosheets, and nanomedicine. Only English full-text articles and reviews relevant to nanomaterial applications in HCC were considered, excluding conference abstracts and non-research items. The analysis encompasses annual publication trends, country-wise publication distribution, prominent institutions, and key journals in the field. Statistical and graphical analyses were performed using GraphPad Prism (v8.0.2) to illustrate publication trends. CiteSpace (6.2.4R) and VOSviewer (1.6.18) software were used to visualize co-citation and keyword networks, highlighting scientific knowledge structures and research hotspots. Notable advancements have emerged as a promising strategy, enabling hepatocyte-specific drug delivery to enhance therapeutic precision and minimize off-target effects. This analysis provides a comprehensive understanding of the evolution of HCC nanomaterials research, key contributing countries, major research institutions, and frequently cited keywords. The findings offer valuable insights into the field's knowledge base, emerging trends, and future directions in HCC treatment with nanomaterials.
