Abstract

Template synthesis inside track-etch membranes is employed to create conducting microtubules of polypyrrole. Within these tubules, glucose oxidase can be adsorbed irreversibly, while retaining its catalytic activity. A glucose sensor is described utilizing the polypyrrole microtubules as mediator. With this sensor glucose can be measured amperometrically in the concentration range 1–30 mM. The sensor is highly selective with respect to other substrates and the sensor response is independent of oxygen concentration. Evidence is presented that in the biosensor direct electron transfer may occur between glucose oxidase and the polypyrrole.

Estimation of effective thickness of Cyclopore polycarbonate membrane by scanning electrochemical impedance microscopy
2022, Journal of Electroanalytical Chemistry
Citation 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.
A new, feasible, on-line method was proposed to determine Cyclopore polycarbonate membrane thickness by scanning electrochemical impedance microscopy (SEIM) technique. The thickness is 8.4 µm, which close to the report technical data. Three effective impedances for equivalent circuit model including Cole-Cole diffusion impedance, Cole-Davidson type impedance and O impedance were firstly proposed for radial diffusion and restricted planar diffusion mode when tip electrode on flat or hole surface in Cyclopore membrane. Data analysis results showed that restricted planar diffusion emerged when tip electrode approach tightly to hole surface. Additionally, SEIM responses on the flat and hole surface were compared and could be applied for topographic imaging in the future work.
Implication of polymer-based immobilized enzymes in medicine
2021, Polymeric Supports for Enzyme Immobilization: Opportunities and Applications
Enzymatic catalysis has been extensively used for wide applications ranging from chemical or pharmaceutical synthesis, food processing, bioremediation, industrial catalysis, etc. under mild conditions with utmost efficacy with respect to chemical processes without any usage of hazardous solvents under mild conditions (temperature: 10°C–50°C, pH: 4.0–8.0) in an inexpensive and environment-friendly way. Enzymes are nontoxic, readily degradable, and can be produced in unlimited quantities; therefore their derived processes are several folds higher economical than chemical-based processes. Enzymes cannot be reused, relatively fragile, much susceptible in the presence of extreme physicochemical environment and it is almost impossible to separate them from reaction mixtures. Immobilization of enzymes onto suitable matrices has been very useful to overcome various shortcomings as mentioned for soluble enzymes. It helps in protecting enzyme from inactivation due to any physicochemical challenges and optimizing in-service performance of enzyme in various industrial processes in addition to drastic decrease in overall cost of industrial productions. The immobilizing matrix (especially its chemical composition and surface morphology) and immobilization methods are the crucial determinants for catalytic efficiency of immobilized enzymes during various industrial processes.
Polymeric materials as immobilization matrix for enzyme have provided versatility in immobilizing vast variety of enzymes involved in various types of applications like oxidation, reduction, inter- and intramolecular transfer of groups, hydrolysis, cleavage of covalent bonds by elimination, addition of groups to double bonds, and isomerization. It is so as polymeric materials can be modulated into various forms such as particles, membranes, and nanofibers. with adjustable physicochemical properties making it more desirous for various enzyme-based industrial applications. Most importantly, with the presence of such versatility in polymeric materials it is possible to improvise catalytic efficiency, stability, reusability cycles, as well as minimizing nonspecific interactions. It is extremely important to scrutinize polymer type and its chemical nature before using it for any specific enzyme immobilization. The chosen polymeric immobilizing support should protect enzyme structure by providing stable enzyme–matrix interactions by thorough understanding type of functional groups (important in enzyme attachment as well as its microenvironment) present on the matrix. The present chapter is based on applications of polymer-based immobilized enzyme in medicine (namely, disease diagnostics, therapeutics, strengthening immune system, and disease marker).

An reagentless glucose biosensor based on direct electrochemistry of glucose oxidase immobilized on poly(methylene blue) doped silica nanocomposites
2012, Sensors and Actuators, B: Chemical
Citation 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].
Conducting polymer nanocomposites have attracted a wide attention in material chemistry and analytical chemistry. In this work, poly(methylene blue) doped silica nanocomposites (PMB@SiO_2(nano)) on glassy carbon electrode (GCE) were synthesized based on a two-step electropolymerization. Compared with poly(methylene blue) film, PMB@SiO_2(nano) had more advantages in facilitating electron transfer between glucose oxidase (GOx) and the electrode surface. GOx immobilized on PMB@SiO_2(nano) underwent a direct and reversible electrochemical reaction involving two-electron and two-proton exchange. A reagentless glucose biosensor using the nanocomposite modified electrode was developed. The calibration curve was linear over a glucose concentration range of 0.01–1.11 mM with a correlation coefficient of 0.998 and a detection limit (3σ) of 3 μM. The apparent Michalis–Menten constant, K_m, for the enzymatic reaction was 0.50 mM. The developed biosensor presented good accuracy, repeatability, reproducibility and stability as well as an excellent ability to resist interference from ascorbic acid and uric acid species. The investigation indicates that PMB@SiO_2(nano) has a good potential for application in construction of the third-generation enzyme biosensor as a conducting matrix material.
