Electrochemical sample matrix elimination for trace-level potentiometric detection with polymeric membrane ion-selective electrodes.

Karin Y Chumbimuni-Torres et al.

Analytical chemistry, 80(15), 6114-6118 (2008-06-24)

Potentiometric sensors are today sufficiently well understood and optimized to reach ultratrace level (subnanomolar) detection limits for numerous ions. In many cases of practical relevance, however, a high electrolyte background hampers the attainable detection limits. A particularly difficult sample matrix

Ca2+ detection utilising AlGaN/GaN transistors with ion-selective polymer membranes.

Mohsen Asadnia et al.

Analytica chimica acta, 987, 105-110 (2017-09-17)

We demonstrate highly selective and sensitive potentiometric ion sensors for calcium ion detection, operated without the use of a reference electrode. The sensors consist of AlGaN/GaN heterostructure-based transistor devices with chemical functionalisation of the gate area using poly (vinylchloride)-based (PVC)

Antiviral, Antibacterial, Antifungal, and Cytotoxic Silver(I) BioMOF Assembled from 1,3,5-Triaza-7-Phoshaadamantane and Pyromellitic Acid.

Sabina W Jaros et al.

Molecules (Basel, Switzerland), 25(9) (2020-05-07)

The present study reports the synthesis, characterization, and crystal structure of a novel bioactive metal-organic framework, [Ag4(µ-PTA)2(µ3-PTA)2(µ4-pma)(H2O)2]n·6nH2O (bioMOF 1), which was assembled from silver(I) oxide, 1,3,5-triaza-7-phosphaadamantane (PTA), and pyromellitic acid (H4pma). This product was isolated as a stable microcrystalline solid

Magnesium-selective ion-channel mimetic sensor with a traditional calcium ionophore.

Jingwei Zhu et al.

Analytical chemistry, 82(1), 436-440 (2009-12-04)

A novel magnesium-selective ion-channel mimetic sensor based on a well-known calcium ionophore, ETH 5234, was demonstrated. Due to different stoichiometry of the ionophore with Mg(2+) and Ca(2+), the sensor exhibits high selectivity to Mg(2+) by controlling ionophore concentration on the
