Abstract: The present disclosure relates to a pH sensor for determining the pH of an aqueous medium at least comprising a polymeric matrix comprising embedded phosphorescent nanoparticles and one or more embedded fluorescent dyes, wherein the phosphorescent nanoparticles comprise transition metal complexes having central atoms selected from the group consisting of Ru, Re, Os, Rh, Ir, Pt and the fluorescent dye comprises fluorescein derivatives according to the following formula I or charged structures thereof, wherein n is greater than or equal to 5 and less than or equal to 20, X?—O—, —OH, —OR4, —NH2, —NH— or NHR4, wherein R4 is selected from the group consisting of C1-C20 alkyl and the R1, R1?, R2, R3 are independently selected from the group consisting of H, D, substituted or unsubstituted C1-C20 alkyl and halogen. Furthermore, the present disclosure comprises a method and a system for determining pH.

Abstract: The invention relates to a fluorescent marker according to the following formula I wherein Fluo is selected from the group consisting of substituted or non-substituted C10-C30 acridone, aminoacridine or pyrene, L is a linker and the moiety X is either a —SO2— or a —PO(OH)— moiety. Furthermore, the present invention relates to the use of the fluorescent markers of the invention, in particular also as a standard in glycan analysis, conjugates of fluorescent markers and glycans, as well as a kit-of-parts containing the fluorescent markers of the invention.

Abstract: The invention relates to novel fluorescent dyes with phosphorylated hydroxymethyl groups, a method for preparing the same as well as to their use in imaging techniques. The fluorescent dyes are coumarin, rhodamine or BODIPY dyes having of one of the following general formulae I-III: wherein W=OP(O)Y1Y2 or P(O)Y1Y2, where Y1 and Y2 independently denote any of the following residues: OH, O(?), ORa and ORb, NHRa and NHRb, NRaRb and NRcRd, ORa and NHRb, ORa and NRbRc, NHRa and NRbRc; and any salt thereof.
