Effect of Plasma Oxidation of Carbon Working Electrode on Its Electrochemical Response
MetadataShow full item record
Screen-printed electrochemical sensors are very perspective because they are much smaller than common electrodes used in electrochemistry, portable, ecological and can be very easily modified in order to increase their sensitivity and selectivity for specific analytes. In this study, plasma treatment was used to modify the carbon working electrode of a screen-printed threeelectrodes system. Plasma treatment was performed using RF plasma discharge in argon/oxygen atmosphere. The plasma modified electrodes exhibited considerable enhancement in electrocatalytic activity towards studied electroactive compounds.
