Photoluminescence and Fluorescence Quenching of Graphene Oxide: A Review
In recent decades, photoluminescence (PL) material with excellent optical properties has been a hot topic. Graphene oxide (GO) is an excellent candidate for PL material because of its unique optical properties, compared to pure graphene. The existence of

Conformational Transitions Accompanying Oligomerization of Yeast Alcohol Oxidase, a Peroxisomal Flavoenzyme [PDF]
Alcohol oxidase (AO) is a homo-octameric flavoenzyme which catalyzes methanol oxidation in methylotrophic yeasts. AO protein is synthesized in the cytosol and subsequently sorted to peroxisomes where the active enzyme is formed.

Determination of epristeride by its quenching effect on the fluorescence of L-tryptophan
A rapid, novel spectrofluorimetric method to determine epristeride (EP) in biological fluids and a pharmaceutical formulation was developed, based on the fact that fluorescence intensity of l-tryptophan could be quenched by EP in the medium of pH=9.0 ...
