Abstract
A sensor implanted in tissues and including a sensing enzyme takes an electrical measurement and compares it to reference curves for the voltage current relationship. The sensor determines whether molecular compounds are present which interfere with the detection of the molecule of interest. If interfering species are found, the measurement voltage is set in a low range to reduce errors, while if the interfering species are not found, the measurement voltage is set in a high range to increase the detected signal.
