“…Copper electrodes have been reported to have a favorable signal-to-noise (S=N) ratio compared to other metal electrodes for the detection of carbohydrates [34]. Detection of glucose is clearly observed at þ0.42 V and is consistent with the observation of Kano et al [35]. Figure 6 illustrates the current response between 0.0 to þ0.6 V at scan rates of 60, 80, and 100 mV s 71 .…”

“…Recently a constant-potential non-fouling amperometric detection method for carbohydrates has been described using a Cu electrode which has been oxidized under controlled conditions (Kano et al, 1996). The detector response appears to be stable for up to a month, and a detection limit of 1OOfmol glucose is reported.…”

“…Esto se debe a que los procesos de oxidación generan una película pasivante o depó-sitos de oxido y/o hidróxido de cobre insolubles, por lo cual las corrientes y las áreas de los picos dependerán en gran medida de las velocidades y mecanismos asociados a la pasivación de la superficie 19 . Las reacciones que experimenta el cobre en un medio fuertemente alcalino se resumen a continuación 9,14,15,27 :…”

“…Se ha demostrado que la oxidación directa del níquel en soluciones de hidróxido lleva a la generación de hidróxido de ní-quel, y aumentando el potencial se puede obtener hasta Ni (III). Este tipo de electrodos modificados se ha usado para obtener señales de oxidación de diferentes clases de moléculas 3,[9][10][11][12][13][14][15][16][17] . El uso de electrodos de cobre para la detección de moléculas tales como, aminoácidos, proteínas, aniones inorgánicos, alcoholes, carbohidratos, está siendo estudiado desde hace algunos años, especialmente en combinación con técnicas cromatográficas y de flujo.…”
