A DNAzyme-induced disposable strip biosensor for visual detection of trace levels of UO <sub>2</sub> <sup>2+</sup> in remote areas
A strip biosensor was constructed for UO<sub>2</sub><sup>2+</sup> detection based on DNAzyme-mediated cleavage and AuNP aggregation, achieving a low detection limit of 160 pM. With a visual mode, high sensitivity, and excellent specificity, our sensor enables on-site detection of UO<sub>2</sub><sup>2+</sup> in remote areas.
