A label-free and signal-on electrochemiluminescence strategy for sensitive amyloid-beta assay

Publication date: Available online 24 June 2019Source: Biosensors and BioelectronicsAuthor(s): Haixin Qin, Xue Gao, Xiaoyan Yang, Wei Cao, Shufeng LiuAbstractDevelopment of a simple, cost-effective and sensitive biosensing strategy is highly desirable to advance the applications in Alzheimer's disease diagnosis. In this paper, we present a simple, label-free and signal-on electrochemiluminescence (ECL) aptasensor for the detection of amyloid-beta (Aβ) peptide using luminol as ECL emitter and in-situ...
