Abstract

original image

Logisch! Eine Serie DNAzym-basierter supramolekularer Strukturen bildet die Grundlage für einen Satz der booleschen Algebra folgender Gatter (siehe Bild). Als Eingabe fungieren zwei Metall-Ionen (Mg2+ und Pb2+), und die Ausgabe zeigen in einem kolorimetrischen Verfahren Gold-Nanopartikel(AuNP)/DNA-Sonden an. Bei Raumtemperatur wurde eine gute Effizienz dieses Systems erreicht.
