Abstract
DNAzymes are DNA molecules with catalytic activities. Analyte-specific DNAzymes can be isolated with a combinatorial biology method called in vitro selection. For example, a Pb2+-specific DNAzyme cleaves its substrate DNA only in the presence of Pb2+. By attaching DNA-functionalized gold nanoparticles to DNAzymes, colorimetric sensors can be designed based on the different colors displayed by the different aggregate states of gold nanoparticles.
