Nitrite has become increasingly significant analyte in analytical chemistry, with its monitoring being essential in various industrial sectors, environmental studies, and healthcare applications. The importance of nitrite detection is evident in the growing number of research publications focused on this topic in recent years. This review specifically concentrates on the development and application of electrochemical sensors. Herein, we provide a comprehensive overview of the methodologies used for nitrite determination, including approaches based on nitrite reduction and oxidation, as well as the use of nitrite biosensors and potentiometric sensors. We attempt to highlight the progress and innovations made in this field since 2010, aiming to give readers a broad understanding of the current state of research and its future directions.
