Abstract: Disclosed is an analysis component and associated systems and methods. The analysis component can be used with an electronic device equipped with a detector for detecting light. The component comprises: a sample holder for holding the sample; a detector site at which a detector, or a detector portion of the electronic device, is to be positioned to detect light reflecting off the sample; and a structural component spacing the sample holder from the detector site by a predetermined distance; wherein the lysis component is configured to allow light from a light source to illuminate the sample such that light reflected by the sample can be received by the detector for analyzing the sample. An associated system comprises the analysis component and a detector for detecting light reflected off the sample.

Abstract: The present invention relates to ?-conjugated fluoroionophores, methods for their preparation, and their use and a method for determining an alkali ion. Fluoroionophoric compounds of the general formula I are described Ionophore-?-Linker-Fluorophore??(I) wherein the Ionophore is an anilino containing crown ether or cryptand with one or more anilino donor moieties as electron donors, forming a stable complex with an alkali metal ion the ?-Linker is an aromatic or heteroaromatic conjugative linking moiety, and the Fluorophore is an electron acceptor moiety. Variation of the ionophoric unit offers a broad spectrum of detectable K+ and Na+-concentrations, ranging from high concentration around 800 mM down to very low concentrations around 3 mM.
