For long-term live-cell fluorescence imaging and biosensing, it is crucial to work with a dye that has high fluorescence quantum yield and photostability without being detrimental to the cells. In this paper, we demonstrate that neutral boron-dipyrro

Studies of extracellular vesicles (EVs), their trafficking and characterization often employ fluorescent labelling. Unfortunately, little attention has been paid thus far to a thorough evaluation of the purification of EVs after labelling, although t

Critical Sensitizer Quality Attributes for Efficient Triplet–Triplet Annihilation Upconversion with Low Power Density Thresholds

Autor: Timo Laaksonen, Nikita A. Durandin, Alexander Efimov, Nikolai V. Tkachenko, Jussi Isokuortti, Elina Vuorimaa-Laukkanen

Publikováno v: The Journal of Physical Chemistry C. 123:22865-22872

Triplet-triplet annihilation upconversion (TTAUC) is a power density-dependent process where photons of low energy are transformed into high energy ones. The most important attributes of efficient TTAUC are quantum yield φTTAUC, power density thresh
