Research Progress in Visualization Technology of Fingerprint Aggregation-Induced Emission Complex Suspensions
摘要
Abstract
Fingerprint,as one of the most important physical evidences found at crime scenes,has seen significant development in its visualization technology.However,it still faces numerous challenges in non-destructive,sensitive,and efficient detection,which to a certain extent limits the direct identification of individuals through fingerprints.In recent years,the application of aggregation-induced emission(AIE)materials in the field of fingerprint development has been increasing,leading to the derivation of the AIE particle suspension development technology.This technology is characterized by high sensitivity,high resolution,high stability,and strong fluorescence performance.Therefore,this review summarizes the domestic and international research status,application trends,and development prospects of AIE complex suspension development technology since 2020.Based on the characteristics of AIE materials such as high sensitivity,high resolution,high stability,and strong fluorescence performance,the methods for enhancing fingerprint development effects using AIE complex suspensions are discussed,including blocking the fluorescence emission of substrates,enhancing the fluorescence intensity of suspensions,and extending the phosphorescence lifetime of suspensions.It focuses on analyzing the development effects of suspensions prepared from organic small-molecule luminescent materials,carbon dot luminescent materials,and metal luminescent complexes on substrates of different types and surface states,covering aspects such as their structure,luminescent mechanism,advantages,disadvantages,and cytotoxicity.Additionally,it introduces the aggregation-caused quenching(ACQ)phenomenon and the advantages of AIE,and lists potential AIE nanomaterials that can be applied to suspension development technology in the future.Finally,the development prospects of AIE complex suspensions in the field of fingerprint development are prospected.关键词
