The focus of this report is electroanalysis performed via screen-printed electrodes.

This study is on current developments concerning ferrocene (FC) and its derivatives on the basis of electrochemical biosensors and sensors. The distinct physiochemical characteristics of FC have enabled the development of new sensor devices, specifically electrochemical sensors. Several articles have focused on the implementation of FC as an electrode constituent while discussing its electrochemical behavior. Furthermore, typical FCdesign-based biosensors and sensors are considered as well as practical examples. The favorable design of FC-based biosensors and general sensors needs adequate control of their chemical and physical characteristics in addition to their surface immobilization and functionalization.

Nanostructured metal oxides such as zinc oxide (ZnO) are considered as excellent material for fabrication of highly sensitive and selective electrochemical sensors and biosensors due to good properties.
