A High-Sensitive Glucose Amperometric Biosensor Based on Prussian Blue Modified Electrodes
Abstract
A first generation amperometric glucose biosensor based on Prussian Blue modified electrodes was developed. Besides exception of noble metals (platinum as usual) the developed biosensor possessed high sensitivity. Linear response dependence on analyte concentration was observed in a range of 10−6 − 5·10−3 M glucose. The current density produced by addition of 10−6 M glucose was 0.18 μ A/cm2. Hydrogen peroxide produced via enzyme reaction was detected by electroreduction. Owing to that reason the biosensor response became independent of the presence of reductants (ascorbate for example). The developed amperometric biosensor was expected to obey requirements for non-invasive diagnostics. There are not principle limits of using other oxidases for Prussian Blue based amperometric biosensor development. Thus one can develop such biosensors for cholesterol, alcohol, glycerol, amino acids ets.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
