Quenching of fluorescence of aromatic molecules by graphene due to electron transfer
, 2010 Investigations on the fluorescence quenching of graphene have been carried out with two organic donor molecules, pyrene butanaoic acid succinimidyl ester (PyBS, I) and oligo(p-phenylenevinylene) methyl ester (OPV-ester, II).

From 2,3-Diazabicyclo[2.2.2]oct-2-ene to Fluorazophore-L, a membrane-bound fluorescent probe for antioxidants [PDF]
, 2004 The aim of this work was to synthesize and to establish a new fluorescent membrane probe for antioxidants by exploiting the exceptional properties of the long-lived fluorophore 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO) alias Fluorazophore-P.

Amplified singlet oxygen generation in metallated-porphyrin doped conjugated polymer nanoparticles [PDF]
, 2018 We report on the mechanism and efficiencies of singlet oxygen O2(1Δg) generation of nanoparticles (NP) of the conjugated polymer (CP) poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) doped with platinum octaethylporphyrin (PtOEP) suspended in water.

Fluorescence quenching by methylcytosine-metal complexation [PDF]
Nucleic Acids Symposium Series, 2006 We report the control of fluorescence emission from the fluorophore fixed on DNA using the methylcytosine-selective addition of an osmium(VI)-bipyridine complex. We synthesized the DNA modified by a microenvironment-sensitive fluorophore, 2-dimethylamino-6-acylnaphthalene.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
