Hemin/G-quadruplex-based DNAzyme concatamers as electrocatalysts and biolabels for amplified electrochemical immunosensing of IgG1.
Hemin/G-quadruplex-based DNAzyme concatamers were utilized as electrocatalysts and biolabels to construct a sandwich-type electrochemical immunosensor for sensitive detection of IgG1 (as a model analyte).
