Sensors, Volume 21, Issue 12

2021 June-2 - 311 articles

Cover Story: Electrochemical sensors are sensitive, portable, fast, inexpensive, and suitable for online and in situ measurements compared to other methods. In this paper, we provide a survey of electrochemical sensors for the detection of water contaminants, i.e., pesticides, nitrate, nitrite, phosphorus, water hardeners, disinfectant, and other emergent contaminants. We focus on the influence of surface modification of working electrodes by carbon nanomaterials, metallic nanostructures, and imprinted polymers and evaluate the corresponding sensing performance. Especially for pesticides, we highlight biosensors, such as enzymatic sensors, immunobiosensors, aptasensors, and biomimetic sensors. We discuss the sensors' overall performance, especially concerning real-sample performance and the capability for actual field application. View this paper.
