摘要
BACKGROUND Recent reviews have outlined the main nanomaterials used in relation to gastrointestinal tumors and described the basic properties of these materials.However,the research hotspots and trends in the application of nanomaterials in gastric cancer(GC)remain obscure.AIM To demonstrate the knowledge structure and evolutionary trends of research into the application of nanomaterials in GC.METHODS Publications related to the application of nanomaterials in GC were retrieved from the Web of Science Core Collection for this systematic review and bibliometric study.VOSviewer and CiteSpace were used for bibliometric and visualization analyses.RESULTS From 2000 to 2022,the application of nanomaterials in GC developed rapidly.The keyword co-occurrence analysis showed that the related research topics were divided into three clusters:(1)The application of nanomaterials in GC treatment;(2)The application and toxicity of nanomaterials in GC diagnosis;and(3)The effects of nanomaterials on the biological behavior of GC cells.Complexes,silver nanoparticles,and green synthesis are the latest high-frequency keywords that represent promising future research directions.CONCLUSION The application of nanomaterials in GC diagnosis and treatment and the mechanisms of their effects on GC cells have been major themes in this field over the past 23 years.
