%X A hybrid nanosystem with impeccable cellular imaging and antioxidant functionality is demonstrated. The microwave irradiation-derived molybdenum trioxide nanoparticles (MoO3 NPs) were surface-functionalized with the cationic dye molecule, methylene blue (MB), which enables superior UV¨Cvisible absorbance and fluorescence emission wavelengths potential for bioimaging. The radical scavenging property of the pristine MoO3 NPs and MoO3¨CMB NPs were studied in vivo using Caenorhabditis elegans as the model system. Heat shock-induced oxidative stress in C. elegans was significantly resolved by the MoO3¨CMB NPs, in agreement with the in vitro radical scavenging study by electron paramagnetic resonance spectroscopy. Hybrid nanostructures of MoO3¨CMB demonstrate synergistic benefits in intracellular imaging with intrinsic biocompatibility and antioxidant behavior, which can facilitate application as advanced healthcare materials toward bioimaging and clinical therapeutics
