DNAzymes are a promising platform for metal ion detection, and a few DNAzyme-based sensors have been reported to detect metal ions inside cells. However, these methods required an influx of metal ions to increase their concentrations for detection. To address this major issue, the design of a catalytic hairpin assembly (CHA) reaction to amplify the signal from photocaged Na<sup>+</sup> -specific DNAzyme to detect endogenous Na<sup>+</sup> inside cells is reported. Upon light activation and in th ...[more]
