Аннотация:We synthesized Prussian Blue (PB) nanoparticles through catalytic reaction involving hydrogen peroxide (H2O2) activation. The resulting nanoparticles display the size-dependent catalytic rate constants in H2O2 reduction,which are significantly improved compared to natural enzyme peroxidase: for PB nanoparticles 200 nm in diameter the turnover number is 300 times higher, for 570 nm diameter nanoparticles – four orders of magnitude higher. Comparing to the known peroxidase-like nanozymes, the advantages of the reported PB nanoparticles are their true enzymatic properties: (i) enzymatic specificity (an absence of oxidase-like activity) and (ii) an ability to operate in physiological
solutions. The ultra-high activity and enzymatic specificity of the catalytically synthesized PB nanoparticles together with high stability and low cost, obviously peculiar to noble metal free inorganic materials, would allow to substitute natural and recombinant peroxidases in biotechnology and analytical sciences.
