This talk will be focused on the synthesis and studies on various types of noble metal-based nanoparticles, which characterize themselves with catalytic activity mimicking enzymes from the class of oxidoreductases. Both the monometallic nanostructures as well as alloyed ones will be compared in terms of peroxidase-, catalase-, glucose oxidase- and superoxide dismutase-like activity. Moreover, core/shell and hollow nanoparticles, in some cases containing residues of templates inside, will be presented and their usefulness in various analytical applications discussed. It should be pointed out, that the latter ones are especially valuable, as they combine the capability for homogenous and heterogenous catalysis. Besides the analytical usefulness, some therapeutic capabilities of some of developed nanoparticles will be also indicated.
