title: Target-induced strand release (TISR) from aptamer-DNA duplex: a general strategy for electronic detection of biomolecules ranging from a small molecule to a large protein.
abstract: We describe a general strategy for electronic aptamer-based biosensor that is based on target-induced strand release (TISR) of a redox-modified aptamer from the aptamer-capture DNA duplex bound on an electrode.
