Abstract

We demonstrate a strategy for pH-programmable self-assembly of DNA nanostructures by taking advantage of the pH dependence of reverse Hoogsteen interactions for a triplex-helix molecular switch. This strategy is successfully applied to the construction of molecular logic gates and imaging of extracellular pH.
