pH dependent multifunctional and multiply-configurable logic gate systems based on small molecule G-quadruplex DNA recognition.


PMID 23358682

Abstract

A variety of logic operations such as XNOR, NOR, AND, NAND, NOT have been designed with pH as an external modulator by choosing thiazole orange (TO) and a c-kit2 promoter quadruplex as two inputs and fluorescence signals of pyridyl bis-indole amide (PBIA) and TO as two outputs.
