A separation-free amperometric immunosensor for vitellogenin based on screen-printed carbon arrays modified with a conductive polymer

Development of disposable low density screen-printed electrode arrays for simultaneous electrochemical measurements of the hybridisation reaction

“…Up to now, most of the screen-printed electrode-based sensors and biosensors are used for single measurements associated with an electrochemical detection [1]. Screenprinted array of electrodes have already been used for heavy metal detection [2], to develop enzymatic biosensors [3][4][5][6] and immunosensors [7,8], or to electroaddress various bioconjugate structures [9,10]; their use for sequence-specific DNA sensing (through the detection of the hybridisation reaction) has to be more investigated.…”

A disposable two-throughput electrochemical immunosensor chip for simultaneous multianalyte determination of tumor markers

“…As shown in Fig. 1C, the surface of bare SPCE was inhomogeneous and uneven due to the randomly distributed carbon particles (Darain et al, 2005), which resulted in the difficulty in producing screen-printed carbon electrodes of equal roughness. So it showed unrepeatable responses for immunoassays.…”

Development of a disposable glucose biosensor using electroless-plated Au/Ni/copper low electrical resistance electrodes

“…These electrodes are widely used, mainly for voltammetric measurements. Carbon paste-based sensors (Yabuki et al, 1992;Ge et al, 1998;Boujtita et al, 2000;Hong et al, 2002;Hart et al, 2002;Fähnrich et al, 2003;Darain et al, 2003;Gao et al, 2003;Honeychurch et al, 2003;Darain et al, 2005;Díaz-González et al, 2005;Ledru et al, 2006;Corgier et al, 2007;Piermarini et al, 2007;Tangkuaram et al, 2007;Honeychurch et al, 2007;Djellouli et al, 2007) are also applicable in coulometry (both amperometry and potentiometry). The wide application of a carbon paste as the matrix of an enzyme electrode is attributed to the simple preparation procedure, which facilitates mass production and therefore, is economical.…”
