The electrocatalytic glucose sensor.

An electrocatalytic glucose sensor is a very useful component of an artificial beta cell in controlling the insulin dosage in the diabetes therapy. The advantage is its potential long-term stability and the disadvantage is its lack of selectivity. The principle and experimental results with different electrolytes will be described. In saline solution the mean deviation in glucose response is up to 15% if the amino acid and urea concentrations raise from minimum to their physiological maximum values.
