As alternatives to natural peroxidases, artificial peroxidases made of inorganic nanomaterials have received great interest for sensing and diagnostic applications. While a variety of artificial peroxidases have been actively developed over the past decade, their relatively low catalytic efficiency together with poor uniformity and difficulty of surface functionalization have not been fully addressed in the area. In this talk, I will introduce our recent work on engineering noble-metal nanostructures as highly efficient and uniform artificial peroxidases. Rational design on nanocrystal engineering, structural characterizations at the atomic level with high-performance electron microscope, and mechanistic understanding with computational modeling will be specified. Applications of the noble-metal artificial peroxidases in chemical sensing and diagnostics of cancer biomarkers will be highlighted. The data and insights provided in this talk may serve as a foundation to inspire future work in the field.
