An amperometric sensor for lactate quantification is presented. The developed biosensor requires only 0.2 U of oxidase, which immobilized in a mucin/albumin hydrogel matrix. By protecting the platinum surface with Nafion membrane, typical interference related to negatively charged species such as ascorbic acid has been minimized practically undetectable levels. Electrochemical properties associated membrane are assessed function concentration. In phosphate buffer solution pH 7.0, linear...
Propofol is a widely used, potent intravenous anesthetic for ambulatory anesthesia and long-term sedation. The target steady state concentration of propofol in blood 0.25–10 μg/mL (1–60 μM). Although can be oxidized electrochemically, monitoring its biological matrixes very challenging due to (i) low therapeutic concentration, (ii) high concentrations easily oxidizable interfering compounds the sample, (iii) fouling working electrode. In this work we report performance characteristics an...
A description of the implementation relaxation method with automatic mesh point allocation for immobilized enzyme electrodes is presented. The advantages this solution coupled reaction-diffusion problems are discussed. numerical simulation technique combined Simplex fitting algorithm to extract kinetic parameters from experimental data. results simulations compared data self-assembled multilayered comprised glucose oxidase (GOx) and an Os modified redox mediator found be in excellent agreement.
A probe beam deflection (PBD) study of ion exchange between an electroactive polymer poly(allylamine)−bipyridyl−pyridine osmium complex film and liquid electrolyte is reported. The PBD measurements were made simultaneously to chronoamperometric oxidation−reduction cycles, be able detect kinetic effects in the exchange. Layer-by-layer (LbL) self-assembled redox polyelectrolyte films with bipyridyl covalently attached poly(allylamine) (PAH−Os) poly(styrene sulfonate) (PSS) have been built by...
The theoretical model presented in part 1 of this work is employed to simulate and fit experimental probe beam deflection (PBD) data Fe(CN)63-/Fe(CN)64- Fe3+/Fe2+ couples. Current deviation dependency on time at constant potential (chronoamperometry chronodeflectometry) analyzed via a new treatment based the migration diffusion properties all species involved. coefficients electroactive are obtained by fitting chronoamperometric curves. Those then respective chronodeflectometric profiles....
