Near-infrared aggregation-induced emission materials:Bibliometric analysis and their application in biomedicalfield

Aggregation-induced emission(AIE)is an intriguing photophysical phenomenon,where specific materials exhibit a remarkable surge in luminescence when brought together in non-ideal solvents or within a solid matrix.Since the concept of AIE wasfirst introduced in 2001,numerous advanced applications have been gradually explored across various domains,including optics,electronics,energy,and the life sciences.Of particular note is the growing interest in the application of AIE systems with near-infrared(NIR)emissive feature in thefield of biomedicine,encompass-ing detection,imaging,and therapeutic interventions.Notably,bibliometric analysis serves as a valuable tool to provide researchers with a comprehensive understand-ing of research achievements and developmental trends in specificfields,which is crucial for academic research.Herein,we present a general bibliometric overview spanning two decades of NIR-AIE development.With the assistance of core scien-tific databases and various bibliometric software tools,we conducted a systematic analysis of annual publications and citations,the most influential countries/regions,leading authors,journals,and institutions,as well as the hot topics related to NIR applications and forward-looking predictions.Furthermore,the application of AIE with NIR properties in the biomedicalfield is also systematically reviewed.
