Special Issue Information
Dear Colleagues,
Electrochemical methods and electroanalytical techniques are promising next-generation analytical tools for various sensing and biosensing applications owing to their exceptional characteristics and advantages over conventional analytical techniques. Electroanalytical techniques are rapid, cost-effective and user-friendly, capable of sensitive and selective measurements, and compatible for miniaturization and out-of-laboratory applications, thereby providing exciting prospects for various fields. Electrochemical approaches can be applied for bioanalysis (e.g., glucose sensing, antigen/antibody or biomarker detection, etc.) as well as for non-biological contaminant analysis (e.g., in agri-food, water and environmental analysis, etc.).
An electrochemical sensor transforms electrochemical information into an analytically useful signal, and is usually composed of two basic components: a chemical (molecular) recognition system and a physicochemical transducer. This device converts chemical reaction into a signal that can be detected via electroanalytical techniques. Biosensors are a type of analytical device that can be classified according to the type of biological sensing element (enzymes, antibodies, aptamers, whole cells, etc.) that they employ or based on the transducer (e.g., electrochemical). The fundamental principle of electrochemical biosensors involves the specific interaction between an immobilized biological sensing element and a target analyte, resulting in alterations in signals (e.g., current, potential and impedance) that correlate with the analyte concentration. The transduction of a chemical or biological signal into an electrical signal can be achieved by various electroanalytical techniques (voltammetry, amperometry or electrochemical impedance spectroscopy, among others).
Electrochemical sensors and biosensors offer a number of advantages, including high sensitivity, low detection limits, and the ability to perform selective and reproducible measurements necessary to meet the rigorous demands of diverse applications. The performance of a biosensor depends on its intrinsic characteristics, such as physicochemical properties, composition, crystal phases, and the morphologies of the materials used for its fabrication. Novel materials and nanomaterials have been extensively used to enhance sensor performance due to their exciting characteristics (size-to-volume ratio, conductivity, surface and interfacial effects, quantum effects, etc.). Thus, determining the appropriate materials is key for developing and fabricating sensors with superior performance for next-generation diagnostics and analysis.
The combination of novel materials and electroanalytical techniques is very promising in further advancing electrochemical sensor and biosensor platforms and devices for various applications, including healthcare diagnostics, biological, biomedical, dairy and agri-food, water and environmental monitoring.
This Special Issue aims to collect the latest developments in advanced and novel materials for electrochemical sensing and biosensing applications to further accelerate innovations in these fields. Original research papers, reviews, and perspective articles are all welcome.
