Abstract

Electrochemical sensors are a class of sensors in which the electrode is the transducer element. These devices (which appeared in the second half of the 20th century) are now found in a wide range of commercial applications. These sensors are notable because of several factors: the use of the electron for signal acquisition, which is considered a clean model for analytical applications, with no generation of waste; miniaturization in portable devices (analyses with microvolumes of samples); fast ...
