ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022 Fifteen new dinuclear arene‐ruthenium (II)‐BODIPY conjugates were synthesized. Despite a fluorescence quenching effect, these conjugates can be used as fluorescent tracers. Their antiparasitic activity but also their toxicity against healthy human foreskin fibroblasts (HFFs) was reduced compared to the parent ruthenium compounds.

Ultra-low threshold pH sensor based on a whispering gallery mode microbubble resonator [PDF]
arXiv, 2023 Laser sensing has a wide range of applications. In this paper, we propose a pH sensing laser with an ultra-low threshold and low sample consumption based on a whispering-gallery-mode microbubble resonator. Rhodamine 6G aqueous solutions with different pH values are used as the lasing gain media, which are injected through the microfluidic channel and ...

Practical Broad-Band Tuning of Dye Lasers by Solvent Shifting [PDF]
, 1986 We have operated a dye laser over a broad wavelength range (593.8-667.0nm) by shifting the dye emission profile with incremental changes of solvent composition. This was accomplished with the laser operating continuously, and only minor adjustment of the
