ElectrochemieSensorik

ElectrochemieSensorik, often translated as electrochemical sensing or electrochemistry sensors, refers to the field of designing and utilizing electrochemical methods to detect and quantify specific analytes. This approach relies on the electrochemical reactions that occur at an electrode surface when it interacts with a target substance. The measurement of electrical signals, such as current, potential, or impedance, provides information about the presence and concentration of the analyte.

The fundamental principle involves an electrochemical cell, typically comprising a working electrode, a counter electrode, and a reference electrode. When an analyte is introduced into the cell, it undergoes an oxidation or reduction reaction at the working electrode. This electron transfer process generates a measurable electrical response. The magnitude of this response is often proportional to the analyte's concentration, allowing for quantitative analysis.

Applications of electrochemie sensorik are diverse and widespread. They are employed in medical diagnostics for blood glucose monitoring and detecting biomarkers, in environmental monitoring for pollutants and water quality assessment, and in industrial process control to ensure product purity and safety. The development of miniaturized and portable electrochemical sensors has also opened avenues for point-of-care testing and in-situ measurements. Key advantages include high sensitivity, selectivity, relatively low cost, and the ability to perform measurements in complex matrices. Ongoing research focuses on improving sensor stability, reducing detection limits, and developing novel electrode materials for enhanced performance.
