The FRET ratio (Cy5/Rox) could be used as a signal for pHe sensing. Using the aptamer as an anchoring element, the DNM exhibited high cell-membrane-anchoring efficiency and excellent specificity. Additionally, relying on the pH-sensitive i-motif and twice FRET signaling mechanism, the DNM possessed a narrow pH response range (0.50 units) and performed imaging of pHe with high resolution. With these advantages, the DNM is expected to be a useful tool for the investigation of the tumor extracellular pH-related physiological process
