A multianalyte flow electrochemical cell: application to the simultaneous determination of carbohydrates based on bioelectrocatalytic detection

Controlled electrophoretic deposition of multifunctional nanomodules for bioelectrochemical applications

“…The incorporation of an enzyme as a highly specific catalytic recognition element, coupled with electrochemical (amperometric or potentiometric) transduction of the recognition event, provides the basis for constructing enzyme-based biosensors, biomedical devices and enzymatic bioreactors (Maestre et al, 2005;Dondapati et al, 2006;Mir et al, 2007). Multi-analyte biosensors have an increasingly important application in the field of medical diagnostics, especially in low-cost self-care devices.…”

Design and application of a flow cell for carbon-film based electrochemical enzyme biosensors

“…Other work cited in the literature regarding the application of a GOx biosensor in flow analysis is not focused on long-term stability evaluation of the electrochemical biosensor. A comparison regarding the sensitivity and the detection limit of the biosensor showed a very good performance of the developed system [31][32][33][34][35]. The 4000 nA mM −1 cm −2 sensitivity of the sol-gel biosensor developed here is much higher when compared with other sol-gel biosensors developed for flow analysis with a sensitivity of 96 nA mM −1 or 81 nA mM −1 cm −2 [31,34] or with other biosensor assemblies such as an epoxy-graphite-TTF·TCNQ-GOD biocomposite developed for flow analysis with a sensitivity of 23.5 nA mM −1 cm −2 [35].…”

Recent developments in electrochemical flow detections—A review

“…The electrodes were employed in a measuring system with on-line microdialysis sampling. Simultaneous FIA determination with six carbon paste biosensors mounted in a radial-flow thin-layer cell was also reported [137]. All enzymatic sensors were mediated with different osmium compounds allowing operation at or below 150 mV vs. Ag/AgCl, which allows interference-free detection of fructose, sucrose, glucose, galactose and lactose in juice and milk samples with sampling frequency of more than 100 h −1 .…”
