supporting information, p. 1189 - 1192 (2015/03/04)
In this report, a vastly improved method for the synthesis of [2.2.3]-triazacryptand (TAC), an excellent K+-selective cryptand, is disclosed, which provides a shorter synthetic route with > fivefold higher overall yield. On the basis of the imp

supporting information; scheme or table, p. 10407 - 10409 (2011/11/06)
We report a novel near-infrared fluorescent calcium probe (KFCA), which has good optical properties such as intense NIR fluorescence emission (670 nm, QY: 0.24), excellent ON/OFF ratio (120-fold), and good wavelength-compatibility with visible-light-emissive fluorophores (Fluo-4, DsRed2), and which is applicable for real-time dual-colour intracellular Ca2+ imaging.
Chromoionophore and method of determining potassium ions
-
Page/Page column 13, (2011/06/25)
The invention relates to methods of determining potassium ions in a sample, wherein the ions are contacted with a compound having chromophoric moiety and an ionophoric moiety, where the ionophoric moiety interacts with the potassium ions present in the sample, resulting in the chromophoric moiety changing its radiation absorption properties in the ultraviolet and visible regions of the spectrum. For example, a change in an intensity of an absorption maximum is measured and the ion concentration is determined accordingly.
A fluorescent sensor with high selectivity and sensitivity for potassium in water
He, Huarui,Mortellaro, Mark A.,Leiner, Marc J. P.,Fraatz, Robert J.,Tusa, James K.
, p. 1468 - 1469 (2007/10/03)
This communication describes a new optical sensor suitable for practical measurement of extracellular (serum or whole blood) potassium. The sensor responds rapidly and reversibly to changes in potassium concentrations typical of whole blood samples. No interferences from clinical concentrations of calcium or pH are observed, and the sodium interference is very minor. Excitation and emission occur in the visible light region. This new potassium sensor is currently used in the Roche OPTI CCA, a commercially available whole blood analyzer. Copyright
