Paragraph 0078-0080; 0085; 0088-0089, (2019/11/21)
The invention relates to a potassium ion fluorescent probe and a preparation method and application thereof (I). The potassium ion fluorescent probe provided by the invention NK1 has the advantages of short synthesis steps and simple structure, wherein, the synthesis steps of the potassium ion fluorescent probe are K ACLE as follows. + To the identification unit BODIPY, the derivative serves TPP as a fluorophore and as a mitochondria targeting group and is matched, so that the potassium ion fluorescent probe has high selectivity and sensitivity in the process of recognizing potassium ions. The NK1 human cervical cancer (HeLa) cell is small in toxic and side effects, high in biocompatibility and capable of targeting mitochondria. In addition, the method provided by the NK1 invention can qualitatively monitor the intracellular or outflow of potassium ions in the cell mitochondria. (by machine translation)
Chromoionophore and method of determining potassium ions

Page/Page column 14, (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.

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
