Significantly Accelerated Direct Electron‐Transfer Kinetics of Hemoglobin in a C60‐MWCNT Nanocomposite Film

“…As a further significant step, we used the C 60 -MWCNT nanocomposite film to modify a glassy carbon (GC) electrode and studied extensively the direct electrochemical behavior of Hb on this surface-modified electrode in aqueous solutions. [25,26] This paper reports the main results of these investigations, including 1) an increase by one order Abstract: The direct electrochemistry of hemoglobin (Hb) was studied in a novel all-carbon nanocomposite film of C 60 -MWCNT (MWCNT = multiplewalled carbon nanotube) and compared with that in bare MWCNT film. The heterogeneous electron-transfer rate constant k s of Hb/C 60 -MWCNT was determined to be 0.39 s…”

Electrochemical Behavior of C60−p-Tert-butylcalix[8]arene Inclusion Complex Film in Mixed Acetonitrile and Water

“…In 1994, Atwood et al [16] and Suzuki et al [17] found that, from their solutions in toluene, C 60 and p-tert-butylcalix [8]arene (L) formed a 1:1 inclusion complex. The interaction between C 60 and L has been confirmed by CP-MAS 13 C NMR, IR spectroscopy and UV-visible spectroscopy [16][17][18][19]. Castillo et al [20] made the Langmuir film of fullerene/calix [8]arene complex.…”

Electrochemical Behavior of Hemin at a C60-γ-Cyclodextrin and Nafion Chemically Modified Electrode

“…It indicates that reduction can form insoluble films with incorporated cations or lead to dissolution. The electrochemical behavior of films of C 60 in an aqueous solution has also been reported [8][9], indicating that both the reduction and the oxidation were completely irreversible. A published procedure [10,11] of embedding C 60 clusters into a water-soluble host molecule of g-cyclodextrin (g-CD) has evoked an investigation of the electrochemical behavior of C 60 films in an aqueous solution.…”
