A facile, sensitive and unmodified Hg2+ homogeneous electrochemical sensor based on bisferrocene signal markers and catalytic hairpin self-assembly (CHA) was built on a gold disk electrode. Three hairpin probes were designed, in which thiol was labeled at both ends of the hairpin probe 1(HP1), while bisferrocene, a redox signal marker, was labeled at both ends of the hairpin probe 2(HP2) and hairpin probe 3(HP3). Due to the Hg2+ mediated thymine-Hg (II)-thymine (T-Hg2+-T) structure, when Hg2+ is introduced, the T-Hg2+-T that occurred be
