Amperometric test strips for point of care biosensors: an overview

Amperometric biosensor strips are a fast and inexpensive way to measure blood metabolites. Although many different compounds can be measured amperometrically by exploiting the same measuring algorithms, the blood glucose monitoring still accounts for the 85% of the biosensors market. The competition between the main industry players promoted the development of sophisticated glucose sensors capable to deliver accurate results while limiting at minimum the user errors. This article presents an overview of the amperometric test strips for point-of-care diagnostics, describing the production and the measurement principle and reviewing some of the most important innovations in the field.
