Most recent application of carbon nanoparticles in electroanalysis are rewieved. After brief introduction on a variety of carbon nanomaterials, the methods of functionalisation or doping of carbon nanoparticles are presented. Next the techniques of their immobilization on the electrode surface are reviewed with special emphasis on layer‐by‐layer deposition and polymer film encapsulation. Then electrochemical properties of carbon nanoparticulate electrodes are presented with the emphasis on their electrocatalytic behavior. Finally the works on bioelectrocatalytic carbon nanoparticulate electrodes modified with enzymes or other biomaterial are reviewed.

“…In particular, we will investigate the possibility to adapt a protocol previously published to immobilize enzymes on such fiber bundles via the encapsulation of carbon nanomaterials in polymer matrices. 34 Because several studies reported performance alterations due to electrode stability problems, 35,36 we also plan to assess the stability of the GCOFs by conducting experiments over long periods of time. Finally, we envision that the optical properties of GCOFs might be exploited to add novel functionalities to membraneless biofuel cells.…”

Gold coated optical fibers as three-dimensional electrodes for microfluidic enzymatic biofuel cells: Toward geometrically enhanced performance

2015

For the first time, we report on the preliminary evaluation of gold coated optical fibers (GCOFs) as three-dimensional (3D) electrodes for a membraneless glucose/ O 2 enzymatic biofuel cell. Two off-the-shelf 125 lm diameter GCOFs were integrated into a 3D microfluidic chip fabricated via rapid prototyping. Using soluble enzymes and a 10 mM glucose solution flowing at an average velocity of 16 mm s À1 along 3 mm long GCOFs, the maximum power density reached 30.0 6 0.1 lW cm À2 at a current density of 160.6 6 0.3 lA cm À2 . Bundles composed of multiple GCOFs could further enhance these first results while serving as substrates for enzyme immobilization. V C 2015 AIP Publishing LLC.
