Green electrochemical sensors, their applications and greenness metrics used: A review

Green analytical methods are important techniques that aim to reduce or eliminate the use of harmful chemicals and waste in various analyses. These methods, based on green chemistry principles, are environmentally friendly and reliable. Electrochemical techniques have an essential role in diverse analyses, and are presented as a superior alternative to existing analytical devices in terms of different parameters. In the present review, we have comprehensively covered electrochemistry‐based sensors that are developed using green chemistry principles and evaluated their performance characteristics and specific working conditions. We here included sensors developed based on potentiometry and voltammetry methodologies
