Electrochemical Biosensing with Carbon Nanotubes

Enhancement of heterogeneous electron transfer dynamics tuning single-walled carbon nanotube forest height and density

“…Engineering of electrodic interfaces are of fundamental importance in various fields [15] since covalent surface modifications of electrodes can sensitively improve the performances of the devices. Noble metal, as gold or platinum are usually applied in sensing research and their specific and selective modification is one of the most wanted issue to achieve.…”

“…These nanostructured electrodes have been called SWCNT forests and they possess useful properties such as the transparency that is needed for optoelectronic applications [10] and field emitters displays [11], the high conductivity that is required for FET systems [12] and the catalytic specification of carbon atoms that may be used for reducing overpotential during water splitting in molecular hydrogen production [13] and for developing new photovoltaic devices [14]. Moreover, through carbon-based modification, bioactive interface functionalization can be efficiently achieved for biosensing purposes [15].…”
