Plasma etching treatment for surface modification of boron-doped diamond electrodes

Poly-l-lysine-modified boron-doped diamond electrodes for the amperometric detection of nucleic acid bases

“…The detection of a specific DNA nucleotide is strongly influenced by the presence of different functional groups on the BDD electrode surface [34,35].…”

Surface structure and electrochemical characteristics of boron-doped diamond exposed to rf N2-plasma

“…5a. Such circuit has been often used for analysing redox behaviour of diamond electrodes [3,9]. For better fitting the double-layer capacitance was substituted in the modelling circuit by a dispersive element Q dl with the admittance 1/Z = Q 0 (jx) n .…”

“…But in many cases the properties of diamond devices are strongly influenced by termination of the active surface area by functional groups of different types, as it has been demonstrated for the cases of hydrogen-, oxygen-and fluorine-terminated surfaces [1][2][3][4][5][6][7][8][9]. Each surface bond structure can be characterised by a specific dipole and dangling bond configuration.…”

“…Each surface bond structure can be characterised by a specific dipole and dangling bond configuration. This may lead to a variety of electrochemical responses of diamond to redox systems [3,[6][7][8][9][10] and vary also the projected flat-band condition of capacitancepotential plots in aqueous solutions [8,[11][12][13]. The latter characteristics could be related to electronic surface states induced by the surface functional groups, which pin the surface Fermi level thus inducing energy band bending at the surface [12][13][14].…”

Enhanced Electrochemiluminescence Employed for the Selective Detection of Methyl Parathion Based on a Zirconia Nanoparticle Film Modified Electrode

“…After that, the glassy carbon electrode was carefully treated by a plasma cleaning machine, which could make an electrode surface covering a large number of oxygen groups. 47 Before the experiment, the bare glassy carbon electrode was cyclic-potential scanned in the potential range -0.2 to 0.6 V in a 1.0 × 10 -3 M K3[Fe(CN)6] solution containing a 0.1 M KCl supporting electrolyte until a pair of well-define redox peaks were obtained.…”
