Amperometric Ethanol Biosensor Based on Integration of Alcohol Dehydrogenase with Meldola's Blue/Ordered Mesoporous Carbon Electrode

Abstract

An amperometric ethanol biosensor was fabricated by integration of alcohol dehydrogenase (ADH) with meldolas blue (MB)/ordered mesoporous carbon (OMC) composite modified glassy carbon electrode (MB/OMC/GCE). The MB/OMC/GCE was highly sensitive for nicotinamide adenine dinucleotide (NADH) measurement (9.1 AE 0.25 mA/ mM) and gave a low detection limit of 0.21 AE 0.02 mM. The ethanol biosensor exhibited a wide linear range up to 6 mM with a lower detection limit of 19.1 AE 0.58 mM as well as a high sensitivity of 34.58 AE 2.43 nA/mM without suffering any interference from some common electroactive compounds.

Carbon Nanotubes‐Ionic Liquid and Chloropromazine Modified Electrode for Determination of NADH and Fabrication of Ethanol Biosensor

“…These fied electrode [48], 10 mM, 25 mM to 1 mM for titanium containing MCM-41 modified glassy carbon electrode [49] and 19 mM, 34.58 nA mM À1 with linear range up to 6 mM for meldolas blue ordered mesoporous carbon composite modified glassy carbon electrode [50]. These data confirm the efficiency of both, CPZ oxidation product as an electron transfer mediator, and IL-CNTs an nanocomposite for immobilization of enzyme and redox mediator.…”

Chiral Biosensors and Immunosensors

“…The same enzyme was immobilized on the surface of electrode and used in that form for preparative purposes (Somers et al, 1998). Although another type of alcohol dehydrogenases were used for biosensor design (Jiang et al 2009) Quinohaemoprotein alcohol dehydrogenase as yet didn't find any analytical application.…”
