Scheme 1From: Facile Bottom-up Preparation of WS2-Based Water-Soluble Quantum Dots as Luminescent Probes for Hydrogen Peroxide and GlucoseSchematic illustration of detection mechanism for glucose by using WS2 QDs. The sensing can be realized via GOx-catalyzed oxidation reaction with dissolved O2 in solution. The PL of QDs can be quenched in proportional to the generated H2O2. (color online)Back to article page
