In this study we present a novel imaging method that combines high resolution cerebral blood flow imaging with a highly flexible map of absolute pO(2). In vivo measurements of pO(2) in animals using phosphorescence quenching is a well established method, and is preferable over electrical probes which are inherently invasive and are limited to single point measurements. However, spatially resolv...

In this experiment you will be concerned with the decay kinetics of the fluorescence of quinine sulfate in water solutions and the physical processes that effect these. Quinine is used as a fluorescence standard because the fluorescence is not quenched (decreased) by oxygen but can be quenched in a controlled manner by adding atomic anions (F-, Cl-, Iand Br-) to the solution . Many molecules re...

We have measured the effects of cofilin on the conformation and dynamics of actin filaments labeled at Cys374 with erythrosin-iodoacetemide (ErIA), using time-resolved phosphorescence anisotropy (TPA). Cofilin quenches the phosphorescence intensity of actin-bound ErIA, indicating that binding changes the local environment of the probe. The cofilin concentration-dependence of the phosphorescence...

Full-type photoluminescence including concomitant fluorescence, delayed and room-temperature phosphorescence from a single organic molecule is used for multi-signal temperature sensing.

Strong ion-pairing in a benzimidazolium-based solid emitter impacts its photophysical properties by promoting fluorescence quenching, enhancing phosphorescence and boosting quantum efficiency under direct triplet-state population.
