Fluorescence correlation spectroscopy (FCS) was developed in order to char acterize the dynamics of molecular processes in systems in thermodynamic equilibrium. FCS determines transport and chemical reaction rates from mea surements of spontaneous microscopic thermally driven molecular concentra tion fluctuations. Since its inception, and particularly in recent years, techni cal and conceptual advances have extended the range of practical applicability and the information obtainable from FCS measurements. Improvements in microscopy, data acquisition, and data processing have greatly shortened the time required for FCS measurements. FCS can now be routinely applied to labile systems such as cells, and for the acquisition of large volumes of data as required for high-throughput screening. Cross correlation methods pro vide a powerful tool for characterizing interactions among different molecular species. Analysis of the amplitude of concentration fluctuations can provide a wealth of information about aggregation/polymerization process and the compositions of mixtures. Furthermore, FCS provides a bridge between conventional measurements of dynamic processes on a macroscopic concentration scale and the currently developing field of single molecule measurements. Both FCS and single mole cule approaches measure directly stochastic fluctuations in molecular pro perties, and so must be analyzed by statistical methods to yield conventional phenomenological parameters. As commonly practiced, FCS yields these phe nomenological parameters, e. g. , diffusion coefficients and chemical rate con stants, directly in terms of a fluorescence fluctuation autocorrelation func tion.

One often hears that nanoscience or, in other words, the knowledge and control of matter at length scales of a few nanometers, will be the scientific frontier of the 21st century. Although it has become almost commonplace, this prediction deserves some justification. The technological and scientific stakes of nanoscience indeed encompass many fields of science: they include the ultimate miniaturization of electronic devices to acquire, store, and process information, and also such basic endeavors as understanding the microscopic processes and patterns responsible for the physical properties of materials, or the many unsolved questions raised by the astoundingly intricate workings of living matter. Although the dream of observing and controlling matter at molecular scales is nearly as old as the very concept of molecules, earlier attempts at practical realizations were hampered by a scarcity of suitable access to the nanoworld. During the last two decades of the 20th century, owing to the several new tools which have been developed to address objects at nanometer scales, the nanoworld appears closer than ever, within our reach! A major class of methods in nanoscience are local probe microscopies such as scanning tunnelling or atomic force microscopies. They require scanning a sharp tip with molecular dimensions across the surface of the sample under study and, by direct action of the tip on the sample, they make nano-manipulations possible. The present book is devoted to another class of methods, the selection and study of single, optically active nano-objects by purely optical means.

In the medical, food, and environmental fields there is a continuous demand for inexpensive and sensitive analytical devices that are reliable, rapid, capable of high-throughput screening, and have low cost per test unit. Small and portable biosensor devices are designed to fulfill most of these requirements, and can be used in laboratory and on-site field testing. This volume discusses major issues in optical, acoustic and electrochemical-based biosensors, biochips, sensing recognition elements, and biosensors for medical and environmental applications. The papers presented at the conference represent basic and applied research studies in the fields of diagnostic assays and biosensor development. Novel technologies, such as arrays of sensors using high-density fiber optics to sense labeled or unlabeled oligonucleotides, and patterned arrays of recognition elements, demonstrated the capability of biosensors to analyze multiple analytes.

Advances in technology have revolutionized the development of light microscopy techniques in biomedical research, thus improving visualization of the microstructure of cells and tissues under physiological conditions. Fluorescence microscopy methods are non-contact and non-invasive and provide high spatial and temporal resolution that other laboratory techniques cannot. This well-illustrated book targets graduate students and scientists who are new to the state-of-the-art fluorescence microscopy techniques used in biological and clinical imaging. It explains basic concepts and imaging procedures for wide-field, confocal, multiphoton excitation, fluorescence resonance energy transfer (FRET), lifetime imaging (FLIM), spectral imaging, fluorescence recovery after photobleaching (FRAP), optical tweezers, total internal reflection, high spatial resolution atomic force microscopy (AFM), and bioluminescence imaging for gene expression. The usage of these techniques in various biological applications, including calcium, pH, membrane potential, mitochondrial signaling, protein-protein interactions under various physiological conditions, and deep tissue imaging, is clearly presented. The authors describe the approaches to selecting epifluorescence microscopy, the detectors, and the image acquisition and processing software for different biological applications. Step-by-step directions on preparing different digital formats for light microscopy images on websites are also provided.

This book examines the chemistry and mode of action of herbicides, insecticides, fungicides and plant growth regulators. It follows crop protection strategies from early discoveries to the present day, emphasising the biochemical targets of the compounds discussed. Chemistry and Mode of Action of Crop Protection Agents provides an in-depth, yet easy to read and understand, review of the major classes of pesticides, explaining also the basis of their activity and selectivity. Throughout, there are many references to allow the reader to pursue areas of special interest, and each chapter contains questions to ensure that the text has been understood. This is the first book on the mode of action of pesticides to have been published in over ten years, and as such will have a very wide audience. It is aimed primarily at graduate level but will also be relevant to the needs of some sixth form and undergraduate courses, as well as to industrialists and advisors in the field of crop protection.

Serving as a general introduction to surface and interface science, this book focuses on basic concepts rather than specific details, and on intuitive understanding rather than merely learning facts. The text reflects the fact that the physics and chemistry of surfaces is a diverse area of research that involves classical scientific and engineering disciplines. As such, it discusses fundamental subjects, such as thermodynamics of interfaces, as well as applied topics including wetting, friction, and lubrication. Following an introduction to the most important techniques and methods, readers will be able to apply simple models to their own scientific problems. Furthermore, manifold high end technological applications are shown together with the basic scientific treatment, for example AFM, surface technology, biotechnology, microelectronics, and biomaterials. The book is written with advanced students of chemistry, physics, materials science, chemical engineering and related subjects who have a basic knowledge of natural sciences and mathematics in mind. In addition, scientists and engineers who are not yet specialists in surface science but want to learn more about this important subject will equally benefit.

Over the last few years there has been a growing concern over the increasing concentration of micropollutants originating from a great variety of sources including pharmaceutical, chemical engineering and personal care product industries in rivers, lakes, soil and groundwater. As most of the micropollutants are polar and persistent compounds, they are only partially or not at all removed from wastewater and thus can enter the environment posing a great risk to the biota. It is hypothesized that wastewater is one of the most important point sources for micropollutants. Treatment of Micropollutants in Water and Wastewater gives a comprehensive overview of modern analytical methods and will summarize novel single and hybrid methods to remove continuously emerging contaminants - micropollutants from the aqueous phase. New trends (e.g. sensor technology, nanotechnology and hybrid treatment technologies) are described in detail. The book is very timely because the new techniques are still in the development phase and have to be realized not only in the laboratory but also on a larger scale. The content of the book is divided into chapters that present current descriptive and analytical methods that are available to detect and measure micropollutants together with detailed information on various chemical, biological and physicochemical methods that have evolved over the last few decades. Treatment of Micropollutants in Water and Wastewater will also enable readers to make well informed choices through providing an understanding of why and how micropollutants must be removed from water sources, and what are the most appropriate and available techniques for providing a cost and technologically effective and sustainable solutions for reaching the goal of micropollutant-free water and wastewater. The book will be suitable for water and wastewater professionals as well for students and researchers in civil engineering, environmental engineering and process engineering fields.
