Signal enhancement for electrochemical detection at glassy carbon electrode modified with phenyl layer

Oxygen electroreduction on chemically modified glassy carbon electrodes in alkaline solution

“…Glassy carbon (GC) [1,4,[6][7][8][9][10][11][12][13][14][15][16][17][18][19], highly oriented pyrolytic graphite (HOPG) [4,6,20,21], boron-doped diamond (BDD) [21][22][23], carbon nanotubes (CNT) [24,25] and other carbon materials have been successfully grafted using the diazonium reduction method. A large variety of surface modifiers can be attached to carbon surfaces.…”

“…Barrier properties of electrochemically grafted aryl moieties have been of considerable interest during the recent decade [2,3,[10][11][12][13]19,20]. Various compounds have been covalently attached to carbon electrode surfaces and their effect on the electron transfer kinetics has been investigated.…”

“…The barrier properties of covalently attached phenyl layers have been studied in several laboratories [8][9][10][11][12]19]. This is the thinnest blocking layer, which can be formed by the diazonium reduction method.…”

Electrochemical amplification using selective self-assembled alkanethiolate monolayers on gold: A predictive mechanistic model

“…We have recently demonstrated that this scheme can be applied using phenyl-modified glassy carbon electrodes [16]. Furthermore, numerous mediation systems are used in bioelectrochemistry [15].…”

Selectivity mechanisms at self-assembled monolayers on gold: Implications in redox recycling amplification systems

“…Redox recycling can improve the performance of current transducers [1][2][3][4][5][6][7][8][9]. These strategies enhance sensitivity by inversion of classical electroanalytical mediation.…”
