Controlled deposition of biological molecules on nanostructured materials is a basic step towards the realisation of biochip components. In this study we report the investigation of the first covalent immobilisation of mass-selected redox protein on a carboxyl-functionalised multi-walled carbon nanotube (MWCNT) electrode surface by means of ion soft landing. The immobilised protein maintains its biochemical properties, displaying an excellent electrochemical behaviour on the electrode Surface. The deposition of mass-selected ions is influenced by several factors, including the charge state and the collision energy of the projectile ions. To elucidate the mechanism involved in the protein reactive landing onto the MWCNT surface, the data obtained from cyclic voltammetry experiments were modelled according to the Marcus theory. The proposed method opens up the way to the development of it new generation of biocomponents, with potential use in biosensors, diagnostics, biofuel cells and bioactive films.
