“…Electrochemical transducer transduces chemical interactions to a meaningful electrochemical signal upon interaction with the analyte and the integrated electronics help to get the data output. 58 Electrochemical sensing platforms, powered by electroanalytical techniques integrated with proper electronics, can offer specificity, sensitivity, reliability, reproducibility, along with the ability to perform on-field operation. We have described three distinct examples for the quantification of harmful pollutant chemical species: cyanide, Cu (II) and atrazine, responsible for major water pollution.…”
