Here, we present the fabrication of novel molybdenum based synthetic nanozymes (Synz) and their applications as a paper-based colorimetric biosensor for the detection of hydrogen peroxide (H2O2) and L-cysteine. Physiochemical characterizations indicate a flower shape architecture with a negative surface potential of -26 eV and presence of carboxyl and hydroxyl groups in Synz. These blue colored Synz has demonstrated photothermal activity under near-infrared region (NIR) laser irradiations (808 nm; 2W/cm2) and possess computerized tomography (CT) contrasting and H2O2 mediated oxygenic properties. Furthermore, Synz are selective and sensitive to H2O2, where the color of the Synz solution has changed from blue to white as well as change in the absorbance spectra in the NIR region (750 nm) when incubated with H2O2. We later coated Synz over whatmann filter paper and monitored change in the color of Synz paper from blue to white.
