- Abstract
Protein immobilization on electrode surfaces remains a technological challenge and is decisive in enhancing biological properties with simplified operational steps. In view of proposing a new direction for protein immobilization, we report the development of a mesoporous framework resulting from the magnetically induced assembly of magnetite nanoparticles decorated with near‐monodisperse gold nanoparticles onto an indium‐tin‐oxide electrode. With an electrochemically active surface area of about 72 cm2 and pores with an average size of 31±1 nm, this magnetically induced mesoporous framework is suitable for the immobilization of small redox proteins. As a proof‐of‐concept, we show the electrochemical process of cytochrome c, where the mesoporous electrode provided a fourfold enhancement for the faradaic currents in comparison to standard polycrystalline gold electrodes.
