Carbon thin films as electrode material in neural sensing

摘要: Abstract For therapeutic purposes, an accurate measurement of dopamine levels in situ would be highly desirable. A novel strategy for the selective determination concentrations based on carbon thin film electrodes is presented this paper. Traditionally, order to make diamond films conductive, they are doped with different concentration boron atoms. Here, varying conductivities were achieved by unbalanced magnetron sputtering. The benefit method that it can performed at room temperature consequently broadening selection suitable substrates. had a wide potential window, which showed strong dependence conductivity. window was largest (4.6 V) most resistive film. On other hand, sensitivity electrode toward not significantly affected In addition, relatively similar behavior respect oxidation observed between various surfaces. slight differences electrochemical among likely caused 1) and/or 2) surface charges and subsequent chemical properties conclusion, stated a-C very neural sensing material.
