Lithium Ion Sensors
The detection and monitoring of lithium in environmental and clinical settings is becoming increasingly important. In this review, sensors incorporating conductive polymers and lithium bronzes are discussed, together with electrochemical and spectroscopic approaches. Ionophore-based methods have been employed extensively, with varying degrees of selectivity and sensitivity, and these are discus...
متن کاملOrtho-phenylenediamine Based Bis-ureas as the Ion Selective Sensors; A QM/MD Study
Density functional theory dispersion corrected (DFT-D3)calculations and molecular dynamic (MD) simulation were applied to investigate the sensing ability of four types of receptors (RCs) composed of the ortho-phenylenediamine based bis-ureas for selective complexation with the anions such as Cl–, Br–, OAC–, PhCO2–, H2PO4– and HSO4– in the gas phase and DMSO. On the basis of the data obtained fr...
متن کاملIon sensors: current limits and new trends
The current status of ion sensors in their main application, clinical chemistry, is highlighted. The reasons for the practical success of sensors in this particular area are discussed together with the expected in ̄uence of novel technical possibilities for the next generation of clinical ion analyzers. A series of recent research results, including the improvement of lower detection limits, the...
متن کاملSolid State Porphyrin Based Mercury Ion Sensors
Among the heavy metals, mercury is often considered the most toxic; moreover, current methods used to sense and quantitate mercury in the environment are expensive and labor intensive. In response, the sensor community has sought new approaches to detect and quantitate mercury. One such approach is the use of porphyrins as selective reagents for the detection of mercury. Porphyrins have shown g...
متن کاملSolid-Contact Reference Electrode for Ion-Selective Sensors
This work presents a flexible miniaturized ion-selective sensor consisting of a solidcontact reference electrode (RE) and ion-selective electrodes (ISE) fabricated on the same foil. The flexible ion sensor was based on AgCl electrodes screen printed on polyethylene terephthalate foil. The RE was formed by casting a mixture of plasticized polyvinylchloride (PVC) and KCl on the AgCl electrode. Th...
