Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include: Advances in theory/and or data analysis Studies of the photophysics of aromatic molecules, solvent, and environmental effects Development of stationary or time-resolved measurements Advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, Chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. PDT/Photodynamic Therapy Typical applications might include: Studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/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.
