چکیده
Following excitation in the range 370-405 nm, the emission spectrum of a cell permeable macrocyclic Eu(III) complex incorporating an N-methylsulfonamide moiety changes form with pH, allowing ratiometric pH measurements in the range 6 to 8.

A FRET based pH probe with a broad working range applicable to referenced ratiometric dual wavelength and luminescence lifetime read out.
A luminescent probe for determination of pH was designed based on a Förster resonance energy transfer (FRET) system, combining a europium chelate as the donor and carboxynaphtho-fluorescein as a pH sensitive acceptor. The FRET system enables referenced pH detection in an exceptional broad dynamic range from pH 3 to 9.

A chemoselective sensor for the citrate anion has been devised, based on a new europium complex that offers ratiometric analysis of the long-lived emission.
متن کاملQuantitative fluorescence ratio imaging of intralysosomal chloride ions with single excitation/dual maximum emission.
Fluorescence ratio imaging is currently being used to quantitatively detect biologically active molecules in biosystems; however, two excitations of most existing fluorescent ratiometric probes account for cumbersome operating conditions for imaging. Thus, a fluorescent ratiometric probe, 6-methoxyquinolinium-dansyl (MQ-DS), for Cl(-) with single excitation/dual maximum emission has been develo...
متن کاملHigh Intensity Solid-state UV Sources for Time-resolved Fluorescence Microcopy
Many naturally occurring substances are intrinsically fluorescent (autofluorescent) when excited with UV or visible wavelengths. Autofluorescence emission typically spans the visible spectrum with a lifetime (?) measured in nanoseconds. Time-resolved fluorescence techniques exploit the large difference in ? that exists between typical autofluorophores and for example, lanthanide chelates (typic...
متن کاملEngineering a FRET strategy to achieve a ratiometric two-photon fluorescence response with a large emission shift and its application to fluorescence imaging.
Two-photon excitation (TPE) probe-based fluorescence imaging has become one of the most attractive diagnostic techniques to investigate biomolecules and biological events in live cells and tissues. At the current stage most of the TPE-based sensing is reflected by fluorescence intensity changes. Nevertheless the mere altering of intensity could be facilely affected by ambient conditions. On the...
