Abstract:
... A simple colorimetric sensing method for the detection of Hg²⁺ was developed by combining enzymatic catalysis with DNA-based hybridization chain reactions (HCRs). Firstly, thymine (T)-rich capture DNA (cDNA) was immobilized on a gold electrode via Au–S bonding. In the presence of Hg²⁺, thymine (T)-rich probe DNA (pDNA) hybridized with cDNA via T–Hg²⁺–T base pairs. Then the HCRs were realized using ...
