Special attention is given optical, electrochemical, electrical, mass-sensitive, magnetic and thermometric sensors. Finally, application examples of chemical sensors in electronic noses and electronic tongues as well as in micro-total analysis systems are briefly discussed.
24 Αυγ 2016 · Introduction. The chemical sensor is an analyzer that responds to a particular analyte in a selective and reversible way and transforms input chemical quantity, ranging from the concentration of a specific sample component to a total composition analysis, into an analytically electrical signal [1, 2], as depicted in Figure 1.
17 Απρ 2022 · Abstract. A chemical sensor can be defined as an inexpensive, portable, foolproof device that can react with excellent selectivity to a specific target chemical (analyte) to produce a measurable signal output at any analyte concentration.
9 Ιαν 2019 · New generations of established sensors, such as metal oxides, are being pushed to new limits by employing nanostructured materials. One of the promises of chemical sensors is that they can be widely deployed to provide comprehensive spatial and temporal analysis of a particular problem.
Electrochemical sensors are made up of three essential components: a receptor that binds the sample, the sample or analyte, and a transducer to convert the reaction into a measurable electrical signal.
1 Ιαν 2024 · This chapter focuses on different electrochemical sensor types such as potentiometric sensors, conductometric sensors, impedometric sensors, coulometric sensors, electrochemiluminescent sensors, as well as voltammetric sensors but explains cyclic voltammetry in detail.
1 Ιαν 2015 · According to the “Cambridge definition,” a molecule (e.g., pH indicator) alone does not make a chemical sensor. Although the term “molecular sensor” is sometimes used to describe a molecule with functions such as a pH indicator, this is more correctly referred to as a “molecular probe.”.
