DNA-nanoparticle micelles as supramolecular fluorogenic substrates enabling catalytic signal amplification and detection by DNAzyme probes

Chem Commun (Camb). 2011 Jan 7;47(1):167-9. doi: 10.1039/c0cc02291h. Epub 2010 Sep 7.

Abstract

Catalytic DNA molecules have tremendous potential in propagating detection events via nucleic acid sequence selective signal amplification. However, they suffer from product inhibition limiting their widespread utility. Herein, this limitation is overcome utilizing a novel fluorogenic substrate design consisting of cooperatively assembled DNA-nanoparticle micelles.
