“…For melamine, Regasa et al developed a melamine-imprinted poly (aniline- co -acrylic acid) (PAA) composite thin film. The hydrogen bonds in this PANI-PAA composite template formed a donor–acceptor pattern with a spacing of 4.8 Å to precisely capture the melamine [ 102 ].…”

Conducting polymers (CPs) are a category of polymeric materials with conjugated main chains. The characteristic electrical and optical properties of CPs can be fine-tuned through controlling the doping states of CPs. Because of their long-term stability in water, CPs have been demonstrated as electroactive biointerfaces and electrode materials especially in aqueous environments. Serving as multifunctional interfaces and organic electrodes for the integration bioelectronics and devices, CPs have been studied and applied in various biological applications. This paper provides a review of conducting polymer–based electrochemical sensors, particularly those used in biological fields. General conducting polymers and derivatives and their main electrochemical sensing platforms with different design of devices are introduced. Cyclic voltammetry, differential pulse voltammetry, chronoamperometry, electrochemical impedance spectroscopy, and quartz crystal microbalance methods and their features are then explored as detection methods for the analysis of drugs and food. To enhance the sensitivity and lower the detection limit of sensing platforms, various CP-based nanocomposites have been designed and developed. Although the electrodes made of CP-based nanocomposites usually outperform those made of pristine CPs, more systematic studies are required to provide insights into the design of nanocomposite-based electrodes. More applications of CP-based sensors for advanced food and drug analyses are expected.

“…To achieve efficient detection, a derivatization reaction must first be performed on Rac, which increases the complexity and uncertainty of the analysis process. LC–MS/MS has been combined with multiple reaction monitoring for the analysis of Rac. , Electrochemical systems offer unique advantages for overcoming the shortcoming of the aforementioned methods. − The apparatus for electrochemical analysis is relatively cheap and easy to operate, and according to a previous study, Rac detection can be completed in 10 min by using this apparatus . The aforementioned apparatus can be made portable by using microfluidic chips or paper microfluidic devices. , Finally, electrochemical analysis has been used for detecting a wide range of biomolecules without the need for pretreatment or separation …”
