Download or read book Systematic Exploration of Indolizine Based Small Fluorescent Molecules written by Youngjun Lee and published by Springer. This book was released on 2018-08-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes an in-depth study of an indolizine-based fluorophore, from understanding of its structure-photophysical property relationship to its application as a useful biological reporter. Organic fluorophores have been extensively used in the field of molecular biology owing to their excellent photophysical property, suitable cell permeability, and synthetic flexibility. Understanding of the structure-photophysical property relationship of a given fluorophore often paves the road to the development of valuable molecular probes to visualize and transcribe biological networks. In this thesis, respective chapters deal with molecular design, organic synthesis, structure-property analysis, and quantum-mechanical interpretation of unexplored family of indolizine-based molecules. This systematic exploration has led to rational development of a new microalgae lipid droplet probe, colorful bioorthogonal fluorogenic probes, and a bright mitochondrial probe, working under live cell conditions. Harnessing the optical properties of a given fluorophore has been an important topic for a couple of decades, both in industry and in academia. This thesis provides useful insights for the improvement and development of unique small fluorescent materials, or optical materials.

Download or read book Advanced Fluorescence Reporters in Chemistry and Biology I written by Alexander P. Demchenko and published by Springer Science & Business Media. This book was released on 2010-09-08 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence reporter is the key element of any sensing or imaging technology. Its optimal choice and implementation is very important for increasing the sensitivity, precision, multiplexing power, and also the spectral, temporal, and spatial reso- tion in different methods of research and practical analysis. Therefore, design of ?uorescence reporters with advanced properties is one of the most important problems. In this volume, top experts in this ?eld provide advanced knowledge on the design and properties of ?uorescent dyes. Organic dyes were the ?rst ?uorescent materials used for analytical purposes, and we observe that they retain their leading positions against strong competition of new materials – conjugated polymers, semiconductor nanocrystals, and metal chelating complexes. Recently, molecular and cellular biology got a valuable tool of organic ?uorophores synt- sized by cell machinery and incorporated into green ?uorescent protein and its analogs. Demands of various ?uorescence techniques operating in spectral, anisotropy, and time domains require focused design of ?uorescence reporters well adapted to these techniques. Near-IR spectral range becomes more and more attractive for various applications, and new dyes emitting in this range are strongly requested. Two-photonic ?uorescence has become one of the major tools in bioimaging, and ?uorescence reporters well adapted to this technique are in urgent need. These problems cannot be solved without the knowledge of fundamental principles of dye design and of physical phenomena behind their ?uorescence response.

Download or read book Design Synthesis and Characterization of Mechanosensitive Dual Fluorescent Dyes as Potential Probes for Biological Applications written by Susantha Ganegamage and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 3 of this dissertation explores a hypothesis that leverages the seesaw photophysical model for N-aryl (2,3- and 1,8-) naphthalimides. The Heagy group initially developed this model to understand the dual fluorescence effect concerning the electron donor or electron-withdrawing substituents. This study envisions the design and synthesis of novel dual fluorescence molecules for a new class of N-aryl-phenanthridinone dyes. The applied photophysical model further investigates these dyes with a substitution pattern opposite naphthalimide systems. Interestingly, predictive computational modeling shows that the substituent pattern, used previously for 2,3-naphthalimides, relies on these groups getting placed on rings in opposite positions for N-aryl-phenanthridinones. Chapter 4, provides an overall conclusion of the and future directions for both parts of the research. In chapter 5, a complete description of experimental data is provided for the characterization of all the dye systems presented. This data includes a detailed synthesis procedure, characterization, purity analysis by HPLC, absorptivity calculation, fluorescence lifetime measurements, quantum yield determination, biological evaluation and fluorescence titration.

Download or read book Design Synthesis and Application of Ultrastable Rylene Dyes for Fluorescent Labeling of Biomolecules written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of organic fluorescent dyes are experiencing a renaissance related to the increasing demands posed by new microscopy techniques for high resolution and high sensitivity. While in the last decade single molecule equipment and methodology has significantly advanced and in some cases reached theoretical limits (e.g. detectors approaching unity quantum yields) unstable emission from chromophores and photobleaching become more and more the bottleneck of the advancement and spreading of single-molecule fluorescence studies. The main goal of this work was the synthesis of fluorophores that are water-soluble, highly fluorescent in an aqueous environment, have a reactive group for attachment to a biomolecule and posses exceptional photostability. An approach towards highly fluorescent, water-soluble and monofunctional perylene-3,4,9,10-tetracarboxdiimide and terrylene-3,4:11,12-tetra carboxidiimide chromophores was presented. A new synthetic strategy for the desymmetrization of perylenetetracarboximides was elaborated; water-solubility was accomplished by introducing sulfonyl substituents in the phenoxy ring. Two strategies have been followed relying on either non-specific or site specific labeling. For this purpose a series of new water-soluble monofunctional perylene and terrylene dyes, bearing amine or carboxy group were prepared. The reactivity and photophysical properties of these new chromophores were studied in aqueous medium. The most suitable chromophores were further derivatized with amine or thiol reactive groups, suitable for chemical modification of proteins. The performance of the new fluorescent probes was assessed by single molecule enzyme tracking, in this case phospholipase acting on phospholipid supported layers. Phospholipase-1 (PLA-1) was labeled with N-hydroxysuccinimide ester functionalized perylene and terrylene derivatives. The purification of the conjugates was accomplished by novel convenient procedure for the removal of unreacted dye from.
