Molecular sensors are powerful because they make it possible to adapt the measurement to the sample instead of a sample to an instrument. Many reporter are available for measuring the chemical properties of a sample, but no purpose-built molecular sensors exist to report a sample's mechanical properties. To address recent interest in the mechanical coordinate of molecular interactions, we developed a prototype molecular sensor, calibrated its force-fluorescence relationship, and adapted the sensor to a cell adhesion assay. This thesis focuses on the considerations for combining force measurement with the environmental and distance sensitivity offered by fluorescence to measure cell-surface adhesion. We showed that DNA can be used as a scaffold to build a sensor molecule, that fluorescence can be used as a reporter of a threshold force, and that introducing cells to the sensor molecules changes the fluorescence properties. Because Cy3 experiences an enhanced intensity sensitivity when conjugated to DNA, the reporter's FRET signal was occluded and we instead activated the sensor complex as a novel, all-fluorescent means of reporting cell-surface proximity. This method for reporting cell-surface separation is significant because it simplifies measurements in thicker and more complex materials interesting to cell-substrate interaction studies.

The key element of any fluorescence sensing or imaging technology is the fluorescence reporter, which transforms the information on molecular interactions and dynamics into measurable signals of fluorescence emission. This book, written by a team of frontline researchers, demonstrates the broad field of applications of fluorescence reporters, starting from nanoscopic properties of materials, such as self-assembled thin films, polymers and ionic liquids, through biological macromolecules and further to living cell, tissue and body imaging. Basic information on obtaining and interpreting experimental data is presented and recent progress in these practically important areas is highlighted. The book is addressed to a broad interdisciplinary audience.

Fluorescence sensing is a rapidly developing field of research and technology. Its target is nearly the whole world of natural and synthetic compounds being detected in different media including living bodies. The application area range from control of industrial processes to environment monitoring and clinical diagnostics. Among different detection methods fluorescence techniques are distinguished by ultimate sensitivity, high temporal and spatial resolution and versatility that allows not only remote detection of different targets but their imaging within the living cells. The basic mechanism of sensing is the transmission of the signal produced by molecular interaction with the target to fluorescent molecules, nanoparticles and nanocomposites with the detection by devices based on modern electronics and optics. In this interdisciplinary field of research and development the book is primarily intended to be a guide for students and young researchers. It is also addressed to professionals involved in active research and product development serving as a reference for the recent achievements. The users of these products will find description of principles that could allow proper selection of sensors for particular needs. Making a strong link between education, research and product development, this book discusses future directions.

This book provides systematic knowledge of basic principles in the design of fluorescence sensing and imaging techniques together with critical analysis of recent developments. Fluorescence is the most popular technique in chemical and biological sensing because of its ultimate sensitivity, high temporal and spatial resolution and versatility that enables imaging within the living cells. It develops rapidly in the directions of constructing new molecular recognition units, new fluorescence reporters and in improving sensitivity of response up to detection of single molecules. Its application areas range from control of industrial processes to environment monitoring and clinical diagnostics. Being a guide for students and young researchers, it also addresses professionals involved in active basic and applied research. Making a strong link between education, research and product development, this book discusses prospects for future progress.

In Fluorescent Protein-Based Biosensors: Methods and Protocols, experts in the field have assembled a series of protocols describing several methods in which fluorescent protein-based reporters can be used to gain unique insights into the regulation of cellular signal transduction. Genetically encodable fluorescent biosensors have allowed researchers to observe biochemical processes within the endogenous cellular environment with unprecedented spatiotemporal resolution. As the number and diversity of available biosensors grows, it is increasingly important to equip researchers with an understanding of the key concepts underlying the design and application of genetically encodable fluorescent biosensors to live cell imaging. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Fluorescent Protein-Based Biosensors: Methods and Protocols promises to be a valuable resource for researchers interested in applying current biosensors to the study of biochemical processes in living cells as well as those interested in developing novel biosensors to visualize other cellular phenomena.

One of the major challenges of modern biology and medicine consists in finding means to visualize biomolecules in their natural environment with the greatest level of accuracy, so as to gain insight into their properties and behaviour in a physiological and pathological setting. This has been achieved thanks to the design of novel imaging agents, in particular to fluorescent biosensors. Fluorescence Biosensors comprise a large set of tools which are useful for fundamental purposes as well as for applications in biomedicine, drug discovery and biotechnology. These tools have been designed and engineered thanks to the combined efforts of chemists and biologists over the last decade, and developed hand in hand together with imaging technologies. This volume will convey the many exciting developments the field of fluorescent biosensors and reporters has witnessed over the recent years, from concepts to applications, including chapters on the chemistry of fluorescent probes, on technologies for monitoring protein/protein interactions and technologies for imaging biosensors in cultured cells and in vivo. Other chapters are devoted to specific examples of genetically-encoded reporters, or to protein and peptide biosensors, together with examples illustrating their application to cellular and in vivo imaging, biomedical applications, drug discovery and high throughput screening.
