An Organically Modified Silicate-Based Ethanol Biosensor

Amperometric ethanol biosensor based on poly(vinyl alcohol)–multiwalled carbon nanotube–alcohol dehydrogenase biocomposite

“…of 3.4%. The sensitivity and response time for the determination of ethanol at the PVA-MWCNT-ADH biocomposite film modified glassy carbon electrode are better than at mediator modified carbon paste electrode and ferrocene encapsulated palladium linked ormosil-based ethanol biosensor (Pandey et al, 2001). …”

Investigation and evaluation of a method for determination of ethanol with the SIRE® Biosensor P100, using alcohol dehydrogenase as recognition element

“…Many biosensors for determination of the amount of ethanol have also been reported (Santos et al, 2003(Santos et al, , 2002Lorenzo et al, 1998;Ramesh and Sampath, 2000;Miertuš et al, 1998;Pandey et al, 2001). The recognition elements have been immobilized on, or in conjunction with, the sensing elements.…”

“…The recognition element is injected within the buffer flow, held inside the reaction chamber for a pre-set reaction time, measured on, and then discarded. This means that the recognition element is only used once, circumventing the problems with inactivation of the recognition element normally associated with traditional biosensors, where the recognition element is immobilized and used many times (Santos et al, 2003(Santos et al, , 2002Lorenzo et al, 1998;Ramesh and Sampath, 2000;Miertuš et al, 1998;Pandey et al, 2001). Soluble recognition elements also allow for rapid change of the recognition element, i.e.…”

Structural Evolution of Octyltriethoxysilane Films on Glass Surfaces during Annealing at Elevated Temperature

“…They have found application in adhesion promotion (2,3), corrosion prevention (4), and wear reduction (5,6), and in the development of optical devices (7,8) and biosensors (9,10). The compounds most commonly used are the tri-chloro-or the tri-alkoxy silanes, which are believed to hydrolyze and then condense with hydroxyl groups on the mineral surface and with one another to produce a chemisorbed film of submonolayer, monolayer, or multilayer thickness.…”
