A low-interference, high-resolution multianalyte electrochemical biosensor.

Electrochemical sensors are used by millions of patients and health care providers every year, yet these measurements are hindered by compounds that also exhibit inherent redox activity. Acetaminophen (APAP) is one such interferent that falls into this extensive class. In this work, an osmium-based redox polymer was used for electrochemical detection in a sensor that was operated at a decreased voltage, allowing for decreased interference.
