Abstract:
We develop a multiplexed self-powered cisplatin sensor based on catalytic repurposing. Cisplatin is reengineered as a catalyst, amplifying both electrical and smartphone-readable colorimetric signals. Sensitivity increases 1000-fold and the dual-signal output enables built-in calibration.
