Originální abstrakt
Recently, nanostructured surfaces have been extensively studied due to their possibility to use them in construction of electrochemical sensors and biosensors. We have prepared tung-sten working electrode modified with gold nanocolumns via galvanic deposition of gold ions through anodic alumina nanoporous template. This nanostructured surface was subsequently electrochemically characterized by cyclic voltammetry using K3[Fe(CN)6]/K4[Fe(CN)6] probe and compared with the results measured on a flat gold electrode. The electroactive areas for both types of electrodes were evaluated and compared. It was found that the nanostructured area affected the response on lower scan rates (up to 25 mV.s-1) and increased the response at higher scan rates (higher than 50 mV.s-1) which is probably related to penetration of electrolyte solution among nanocolumns. Nevertheless, this fact can help in speed of analyses of huge amount of samples
