DNAzymes have attracted increasing interest in developments of gene tools, therapies, and biosensors. Among them, G-quadruplexes are widely used as the key structure elements to activate catalytic competency specific cofactors, such hemin, but there is a great demand diversify using other more straightforward DNA structures fully matched duplex (FM-DNA). However, perfect base pairs limit DNAzym...
