Estimation of effective thickness of Cyclopore polycarbonate membrane by scanning electrochemical impedance microscopy
2022, Journal of Electroanalytical ChemistryCitation Excerpt :Track-etched polycarbonate membranes are commonly used as filters in fuel cells [15], DNA and protein sensing [16,17], infrared spectroscopy [18] and flow electrophoresis [19]. In diagnostic fields, the membrane is also used as a control barrier in glucose sensors [20]. In all above cases, the single pore volume on the membrane needs to be known.

2012, TalantaCitation Excerpt :Examples of these include cholesterol oxidase [126], glucose oxidase, sulphite oxidase, urease, XOD, [105,106], PNP [122] and urate oxidase. Several researchers have reported the successful fabrication of biosensors for the determination of various substances, such as glucose [57–96], urea [97–100], l and d amino acids [101], sulphite [102,103], DNA [56,104], Hx [105,106], cholesterol [107–119] and phosphate [120–122]. Of these, the development of biosensors based on electrochemical detection has attracted most interest in recent years.
An reagentless glucose biosensor based on direct electrochemistry of glucose oxidase immobilized on poly(methylene blue) doped silica nanocomposites
2012, Sensors and Actuators, B: ChemicalCitation Excerpt :Electrons can be transferred directly from GOx to the electrode via conducting polymer. For example, Koopal et al. described a glucose biosensor based on direct electrical communication from GOx to electrode through polypyrrole incorporated into the nanopores of a filtration membrane [6]. Lu et al. studied the direct electron transfer of GOx immobilized in a layer of polyaniline [7].
