title: A cell-surface-anchored ratiometric i-motif sensor for extracellular pH detection.
abstract: A FRET-based sensor is anchored on the cell surface through streptavidin-biotin interactions. Due to the excellent properties of the pH-sensitive i-motif structure, the sensor can detect extracellular pH with high sensitivity and excellent reversibility.
