title: Crystal violet as a fluorescent switch-on probe for i-motif: label-free DNA-based logic gate.
abstract: The first application of crystal violet as a selective fluorescent switch-on probe for i-motif DNA has been reported. This interaction has been exploited to develop a label-free DNA-based "OR" logic gate for potassium and hydrogen ions.
