The literature data present some examples of sensors for the detection of several antibiotics and antihypertensive and anti-inflammatory drugs currently used in urban areas. The detection of antibiotic residues in environmental samples through the use of various disposable electrochemical sensors has proved the capacity of these sensors for fast, low-cost, and sensitive detection. Tetracyclines, as an important class of antibiotics, were investigated on gold SPEs using cyclic voltammetry... 

Controlled potential techniques have shown to be useful tools to characterize the electrochemical behavior of organic compounds. Particularly, cyclic, convolution and square wave voltammetries, controlled potential electrolysis, and digital simulation provide valuable information, which allows elucidating the electrochemical reaction mechanism, and the determination of thermodynamic, kinetic and diffusion parameters (Bard Faulkner, 2001). In addition, the square wave voltammetry is particularly a fast and sensitive technique to detect and quantify a given substrate considering its ability to discriminate against capacitive currents (Osteryoimg O Dea, 1987 Mirceski, Komorsky-Lovric Lovric, 2007).
