Artificial peroxidases made of inorganic nanomaterials have received great interest for sensing and diagnostic applications in the last decade. While a variety of artificial peroxidases have been actively developed, their relatively low catalytic efficiency together with poor uniformity and difficulty of surface functionalization have not been fully addressed in the field. In this talk, I will introduce our recent work on engineering noble-metal nanostructures as well-defined and highly efficient 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 diagnostics of cancer biomarkers will be highlighted.
