title: Enhanced catalytic DNAzyme for label-free colorimetric detection of DNA.
abstract: A DNAzyme-based label-free method for the colorimetric detection of DNA is introduced, with a supramolecular hemin-G-quartet complex as the sensing element and a 36-mer single-strand DNA as the analyte that is detected at 10 nM.
