This book was released on 2017 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical imaging and spectroscopy technologies offer the ability to provide structural and functional information in a fast, low-cost, ionizing radiation free, highly sensitive and high throughput fashion. The diverse contrast mechanisms and complementary imaging platforms form the foundation for the application of optical imaging in pre-clinical studies of pathophysiological development as well as direct clinical application as a tool for diagnosis and therapy. Fluorescence imaging techniques have been one of the most rapidly adopted methods in biology and biomedicine. Visualization of biological processes and pathologic conditions at the cellular and tissue levels largely relies on the use of exogenous fluorophores or their bioconjugates. Some fluorescent molecular probes provide usable contrast for disease diagnosis due to their responsiveness to interactions with other molecular species and/or immediate microenvironment. As a result, understanding exogenous fluorescent contrast mechanisms will allow the development of efficient strategies for biomedical fluorescence imaging. The present work focuses on exploring novel fluorescent molecular probe strategies for imaging cancer and cardiovascular diseases. We have developed a platform for synthesizing activatable fluorescent molecular probes using the fluorescence quenching properties of copper (II) ions. We used these activatable probes for rapid imaging of cancerous tissue in vivo in mice. While developing these molecular probes, we discovered an unexpected molecular interaction that yields stable dimeric molecules. This finding can potentially enable the development of new molecular entities for modifying the signaling properties of fluorescent dyes to minimize background fluorescence. Although planar fluorescence imaging methods using exogenous molecular probes provide rapid information about molecular processes in vivo, extraction of depth information require complex data acquisition and image analysis methods. By designing a dual emission fluorescent probe incorporating two spectrally different fluorophore systems, we developed a method to successfully estimate the depth of fluorescent inclusions from planar imaging data and demonstrated the potential of using this approach to locate a blood vessel and tumorous tissue in mouse in vivo. An important feature of fluorescence methods is the availability of various techniques that provide complementary information. Combining the fluorescence intensity and lifetime properties of a biologically targeted near infrared fluorescent probe, we demonstrate an effective way to distinguish specific from nonspecific uptake mechanisms in cancer cells, an approach that can be translated in vivo. Alternatively, dynamic fluorescence imaging technique expands the scope of applications to include detection and estimation of the size of circulating cancer cells and clusters. The approach developed in this work could allow longitudinal monitoring of these cells, which are implicated in cancer metastases. To circumvent the shallow penetration of light using optical methods, we developed multimodal imaging approaches by incorporating a radionuclide for nuclear imaging into a broad spectrum near infrared fluorescent tumor targeting agent. This molecular construct allows for noninvasive whole body nuclear imaging of tumors, followed by fluorescence image guided resection. In each of these areas, novel fluorescent molecular probes were developed, characterized and applied to solve critical biomedical problems.

Download or read book Fluorescent Energy Transfer Nucleic Acid Probes written by Vladimir V. Didenko and published by Springer Science & Business Media. This book was released on 2008-02-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescent nucleic acid probes, which use energy transfer, include such constructs as molecular beacons, molecular break lights, Scorpion primers, TaqMan probes, and others. These probes signal detection of their targets by changing either the intensity or the color of their fluorescence. Not surpr- ingly, these luminous, multicolored probes carry more flashy names than their counterparts in the other fields of molecular biology. In recent years, fluor- cent probes and assays, which make use of energy transfer, have multiplied at a high rate and have found numerous applications. However, in spite of this explosive growth in the field, there are no manuals summarizing different p- tocols and fluorescent probe designs. In view of this, the main objective of Fluorescent Energy Transfer Nucleic Acid Probes: Designs and Protocols is to provide such a collection. Oligonucleotides with one or several chromophore tags can form fluor- cent probes capable of energy transfer. Energy transport within the probe can occur via the resonance energy transfer mechanism, also called Förster tra- fer, or by non-Förster transfer mechanisms. Although the probes using Förster transfer were developed and used first, the later non-Förster-based probes, such as molecular beacons, now represent an attractive and widely used option. The term “fluorescent energy transfer probes” in the title of this book covers both Förster-based fluorescence resonance energy transfer (FRET) probes and probes using non-FRET mechanisms. Energy transfer probes serve as molecule-size sensors, changing their fluorescence upon detection of various DNA reactions.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : My thesis is focused on the development of fluorescent probes for biosensing and bioimaging within specific organelles. My main research efforts are mainly focused on the design, synthesis and biological applications of these new molecular probes. These new fluorescent probes I developed can be manipulated through the chemical modifications for binding to specific organelles capable of reporting localized bioinformation. Compared to the currently commercially available organelle-specific fluorescent stains, the advantages of the newly synthesized fluorescent probes include low cytotoxicity, high photostability, and long fluorescence lifetimes. These features are crucial for long-time tracking study of biological processes. Research on fluorescent probes with both analyte responsiveness and organelle targetability is a new and emerging area that has attracted increasing attention over the past few years. Because of their high sensitivity, specificity and fast response, these novel fluorescent probes have been proven to be useful tools for facilitating biomedical research. I have further extended the diversity by developing organelle-specific responsive probes capable of detecting changes in biomolecular levels and the microenvironment. My future research efforts give more considerations of the "low-concern" organelles, such as the Golgi apparatus, the endoplasmic reticulum, and ribosomes. Considering the tiny sizes of subcellular organelles, we anticipate that better visualization of the cellular events within specific organelles will rely on super-resolution optical microscopy with nanoscopic-scale resolution.

This book was released on 2019-09-11 with total page 216 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.

Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive reference on fluorescent nanodiamond physical and chemical properties and contemporary applications Fluorescent nanodiamonds (FNDs) have drawn a great deal of attention over the past several years, and their applications and development potential are proving to be manifold and vast. The first and only book of its kind, Fluorescent Nanodiamonds is a comprehensive guide to the basic science and technical information needed to fully understand the fundamentals of FNDs and their potential applications across an array of domains. In demonstrating the importance of FNDs in biological applications, the authors bring together all relevant chemistry, physics, materials science and biology. Nanodiamonds are produced by powerful cataclysmic events such as explosions, volcanic eruptions and meteorite impacts. They also can be created in the lab by high-pressure high-temperature treatment of graphite or detonating an explosive in a reactor vessel. A single imperfection can give a nanodiamond a specific, isolated color center which allows it to function as a single, trapped atom. Much smaller than the thickness of a human hair, a nanodiamond can have a huge surface area that allows it to bond with a variety of other materials. Because of their non-toxicity, nanodiamonds may be useful in biomedical applications, such as drug delivery and gene therapy. The most comprehensive reference on a topic of rapidly increasing interest among academic and industrial researchers across an array of fields Includes numerous case studies and practical examples from many areas of research and industrial applications, as well as fascinating and instructive historical perspectives Each chapter addresses, in-depth, a single integral topic including the fundamental properties, synthesis, mechanisms and functionalisation of FNDs The first book published by the key patent holder with his research group in the field of FNDs Fluorescent Nanodiamonds is an important working resource for a broad range of scientists and engineers in industry and academia. It will also be a welcome reference for instructors in chemistry, physics, materials science, biology and related fields.

This book was released on 2024-05-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to popular belief, appealing to the sense of sight is more powerful than appealing to the sense of hearing, which could be the origin of the adage ""Seeing is believing."" Technologies that allow researchers to ""see into the body"" or ""see into cells"" are crucial for both basic biological processes research and the detection and treatment of disease. It is ideal for the procedures to be non-invasive, meaning they shouldn't include slicing into the body or separating its components. Thus, in the biomedical sciences, methods for visualising physiological or pathological changes in the body and cells have grown in significance. Contributing to the regulation of numerous physiological processes and playing critical roles in preserving the healthy development of living bodies, a few significant biological species and their microenvironments manage a complex and sensitive dynamic balance in life systems. Living things can develop a variety of illnesses or even pass away if their homeostasis is disturbed. Real-time monitoring of these biological species and their microenvironments during various physiological and pathological processes is therefore extremely important. One of the most effective methods for real-time imaging in biological samples is the use of fluorescent probe-based approaches. Small-molecule fluorescent probes have developed into effective instruments for exploiting light to enhance the field of cell biology research, find novel medications, identify pollutants in the environment, and increase cancer diagnosis. The growth of the fluorescent probe research community-which was tiny in the late 20th century but now comprises over a hundred research groups worldwide-correlates with these uses. It took scientists with a lot of courage from many different professions to join this expansion. In this book, pyrene, coumarin, and naphthalimide are among the fluorescent dyes that are most frequently employed for fluorescence imaging.
