Abstract
Understanding the relationships between molecular organization and dynamics of a complex system is very important to understand the photophysical properties of such system. This paper focuses on a novel strategy based on single molecule spectroscopy and single molecule localization microscopy to elucidate the photostability and localization of a fluorophore molecule on a 2D biomembrane. Improvement of in-plane resolution of a signal in a nano-dimension within the diffraction limit has been discussed in a new way. And, how this better in-plane resolution information can be used for precise localization of a single molecule on a 2D system has also been discussed.
期刊介绍：
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. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe 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.
