It′s logical! A set of DNAzyme-based Boolean logic gates consists of a series of supramolecular structures (see picture). Two metal ions (Mg2+ and Pb2+) act as inputs and gold nanoparticle (AuNP)/DNA probes as output reporters for colorimetric detection. Fast performance of the logic system at ambient temperature is achieved.
