title: DNA pseudoknot-functionalized sensing platform for chemoselective analysis of mercury ions.
abstract: A novel, simple, signal-enhanced electrochemical sensor was designed for sensitive and selective determination of mercury ions by using target-triggered conformational change of DNA pseudoknots with the assistance of auxiliary DNA strands.
