abstract = {Multi-walled carbon nanotubes (MWCNTs) double functionalized with redox-active ferrocene and biotin (Fc–Biot-MWCNTs) were synthesized and used for the electrochemical detection of avidin. After dispersion in perfluorosulfonated polymer Nafion and immobilization on the electrode surfaces, the cyclic voltammetry response of the modified electrodes showed in aqueous medium a quasi-reversible one-electron system at 0.46V vs. SCE, assigned to the bound ferrocene/ferrocenium redox couple. Upon the addition of avidin in the range 0.9–20nM, a stepwise decrease of both anodic and cathodic peak currents ascribed to the ferrocene was observed. These electrochemical changes are specifically due to the formation of biotin–avidin complex and are explained by complexation-induced modifications in the environment of covalently bound ferrocene.},

abstract = {Redox-active ferrocene was assembled on gold surfaces through the hydrogen bonding interactions between adenine-substituted ferrocene and a uracil-terminated organothiol monolayer. The surface coverage of ferrocene Γ could be varied from ca. 4×10−11 to 2.0×10−10molcm−2 by diluting the thiol-modified uracil derivative with inert 1-octanethiol. A decrease in the apparent electron transfer rate constant for ferrocene, kapp, from ca. 50 to 10s−1 was observed upon increasing Γ.},
