Amplified colorimetric detection of tetracycline based on an enzyme-linked aptamer assay with multivalent HRP-mimicking DNAzyme

Analyst, 2019, Advance Article DOI: 10.1039/C8AN02284D, PaperXin Gong, Xiao Li, Taiping Qing, Peng Zhang, Bo Feng An indirect competitive enzyme-linked aptamer assay (ELAA) with multivalent HRP-mimicking DNAzyme for colorimetric detection of tetracycline. Aptamer modified multivalent HRP-mimicking DNAzyme exhibited high selectivity and enhanced catalytic capacity, which improved the detection sensitivity greatly.
