• Dps protein molecules successful localization in Si nanowires array. • Integration of molecular culture with Si nanowires. • Si nanowires 3D developed surface compatible for Dps protein molecules localization. Successful integration of the ferritin Dps protein of native origin with the developed surface of a silicon nanowires array has been demonstrated. The possibility of protein localization has been realized for different types of silicon nanostructures in terms of conductivity, different volumes of wires arrays pores available for this localization, and different wire array morphology. The observed results show the possibility of effective removal of buffer solution salts from the cultural medium, in which ferritin Dps remains on the 3D-developed porous surface of silicon nanowires. The findings demonstrate the effectiveness of a simple and affordable method to functionalize the engineered and technologically advanced silicon nanowire surface with a nanoscale ferritin Dps bioculture.
