英文摘要	co3o4-modified prussian blue (pb) nanocubes (pb@co3o4) were prepared by a simple water-bath method with cocl2 as the co source. tem, sem, xrd and xps results indicated the uniform distribution of island-like spinel-phase co3o4 nanoparticles (nps) on the surfaces of the pb nanocubes (similar to 200 nm). the pb@co3o4 nps exhibited both intrinsic oxidase-and peroxidase-like activities and were observed to rapidly oxidize the peroxidase substrate 3,30,5,50-tetramethylbenzidine (tmb) with or without hydrogen peroxide at acidic ph values. in contrast, pb nanocubes or co3o4 nps alone could not efficiently oxidize tmb without h2o2. the enzyme-like activity of pb@co3o4 nps was also influenced by the working ph and temperature. based on the oxidase-like activity of pb@co3o4 nps, a facile colorimetric biosensor for detection of glutathione was successfully fabricated, and displayed a linear range of 0.1 to 10 mu m (r = 0.9740) and limit of detection of 0.021 mm (s/n = 3). these results demonstrate the potential applications of pb@co3o4 nps in bioanalysis and biodetection.
