Description
Summary:The immobilization of ferrocene’s amino derivatives onto carboxyl-functionalized multiwalled carbon nanotubes (MWCNTs−COOH) electrodes has been carried out to test the ability of the ion reactive landing procedure to realize chemically modified electrodes. The ionic species involved in the ion reactive landing procedure were structurally and energetically characterized by the joint application of collisionally induced dissociation mass spectrometry and theoretical calculations. Furthermore, the modified surface was analyzed by spectroscopic and voltammetric techniques and the electron mediation of the ferrocene derivatives demonstrated in the presence of laccase. Data obtained put in evidence a strong interaction between the landed molecules and the MWCNTs surface.
