A human telomeric DNA-based chiral biosensor†
Abstract
Here we report an electrochemical DNA (E-DNA) chiral sensor that can distinguish zinc-finger like metallo-supramolecular enantiomers based on human telomeric G-quadruplex formation specifically induced by one of the enantiomers. The assay is easy to operate and reusable with an enantioselective recognition ratio higher than 5.
