Abstract

An on-cell aptamer sensor has the potential to reveal cell–cell communications by signalling molecules. We attempted to design new fluorescent aptamer sensors for the sensing of IFN-γ and adenine compounds on cells. BODIPY-labeled external quencher-free aptamer sensors have allowed a turn-on detection of the target molecule with improved off/on efficiency.
