  • Title: Ionic liquid decorated AIE luminogen for selective detection of HSA in biofluids and early disease screening.
    Author: Gao L, Lin X, Chen X.
    Journal: Talanta; 2020 May 15; 212():120763. PubMed ID: 32113536.
    Abstract:
    The precise evaluation of human serum albumin (HSA) contents in biofluids is critical due to its important physiological functions. A fluorescent luminogen TPE-IL is facilely fabricated in present study by decorating the aggregation induced emission (AIE) dye E-1,2-bis(4-hydroxyphenyl)-1,2-diphenylethylene (TPE-OH) with ionic liquid (IL) HOOCMIMBr. The hydrophobic and hydrogen-bond interactions between the amino acid residues of HSA and TPE-IL lead to the spontaneous and energetically favorable docking of TPE-IL molecules in the hydrophobic subdomain of HSA, inducing the significant fluorescence enhancement of this sensor. Highly sensitive and selective detection of HSA is accomplished in the linear range of 0.02-10 μg/mL, with a detection limit of 0.007 μg/mL. The practicability of this sensor is validated by the accurate detection of HSA contents in human serum and urine samples. A glass slide-based visual sensing platform is also constructed to offer simple and fast HSA content evaluation in serum for early disease screening.
