摘要

DNA hybridization can finely regulate the intrinsic glucose oxidase like catalytic activity of AuNPs owing to the marked difference in adsorption of single- and double-stranded DNA on its surface. A sensing strategy for DNA and microRNA is presented; in a different approach, this DNA-regulated AuNP catalysis was coupled with AuNP-mediated seed growth, which was monitored in real time and at a single-nanoparticle level.
