journal of Fluorescence is an international forum for peer-reviewed original articles that advance the practice of this established spectroscopic technique. Coverage includes advances in theory and data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, advances in fluorescence microscopy, imaging, photobleaching, and phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry analysis, immunology, high throughput screening and drug discovery, DNA sequencing and arrays, genomics and proteomics. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
