Carbon microelectrodes have been implemented as sensing phases in order to improve the efficiency of the electrochemical sensing in capillary electrophoresis microchips. Surface and embedded carbon microelectrodes were fabricated on glassy substrates using a laser lithography technique. Both types of microelectrodes were successfully verified and, in the case of embedded microelectrodes, are proving to be an excellent alternative to increase the sensitivity of biosensors based on capillary electrophoresis.
