0D MoSe2 quantum dots are prepared via solvothermal exfoliation. Quantum confinement induces blue-shifted excitonic transitions and excitation-dependent photoluminescence. Combined with peroxidase-like activity, these properties enable sensitive colorimetric biosensing for hydrogen peroxide detection.
