A Universal Paper-Based Electrochemical Sensor for Zero-Background Assay of Diverse Biomarkers

9 Apr 2019

Abstract excerpt

This paper describes a universal paper-based electrochemical sensing platform that uses a paper modified with signal molecule-labeled DNA and a screen-printed electrode along with target recognition solutions to achieve the detection of multiple types of biomarkers. These assays rely on the target-induced synthesis of Mg 2+ -dependent DNAzyme for catalyzing the cleavage of substrate DNA from paper, which have...
