Summary : Electroanalytical Applications of Quantum Dot Based Biosensors describes electroanalytical applications of quantum-dot based sensors, including protein-ligand interactions, molecularly imprinted polymer-based nanosensors, electrochemical DNA biosensors, electroluminescence for biomarker analysis, photoelectrochemical techniques, enzyme based nanobiosensors, electrochemical immunosensors, and quantum dot modified nanosensors in drug analysis. This book is an important reference source for materials scientists and engineers who are looking to increase their understanding of how quantum dots are being used to create new types of sensor. Quantum dots are hybrid organic/inorganic nanoparticles with novel physical properties. They have two components: an inorganic core and optically active coated shell. Moreover, surface coatings can be applied to quantum dots to modify the particle as needed for experiments. Hydrophilic coatings prevent leaking of metal cargo from the core, enhancing the solubility in biological contexts and bind molecules such as receptor-ligands, anti-bodies, therapeutic and diagnostic macromolecules for enhanced effects. Their high surface-to-volume ratio allows multiple functional groups to attach onto the surface of the particles at constant surface-volume. Silicon-, gallium-, indium- or germanium-based, cadmium-based and carbon-based quantum dots, etc., have already been used in many applications such as imaging probes for the engineering of multifunctional nanodevices. Outlines quantum dot-based applications for food, clinical and environmental science Shows how the properties of quantum dots make them effective ingredients in biosensing applications Assesses the major challenges in integrating quantum dots in biosensing systems

Nanoscale sensors can be used for a wide variety of applications, including the detection of gases, optical signals, and mechanical strain, and can meet the need to detect and quantify the presence of gaseous pollutants or other dangerous substances in the environment. Gas sensors have found various applications in our daily lives and in industry. Semiconductive oxides, including SnO2, ZnO, Fe2O3, and In2O3, are promising candidates for gas sensor applications. Carbon nanomaterials are becoming increasingly available as “off-the-shelf” components, and this makes nanotechnology more exciting and approachable than ever before. Nano-wire based field- effect transistor biosensors have also received much attention in recent years as a way to achieve ultra-sensitive and label-free sensing of molecules of biological interest. A diverse array of semiconductor-based nanostructures has been synthesized for use as a photoelectrochemical sensor or biosensor in the detection of low concentrations of analytes. A novel acoustic sensor for structural health monitoring (SHM) that utilizes lead zirconate titanate (PZT) nano- active fiber composites (NAFCs) is described as well.

Summary : Since four decades, rapid detection and monitoring in clinical and food diagnostics and in environmental and biodefense have paved the way for the elaboration of electrochemical biosensors. Thanks to their adaptability, ease of use in relatively complex samples, and their portability, electrochemical biosensors now are one of the mainstays of analytical chemistry. In particular, electrochemistry has played a pivotal role in the development of transduction methods for biological processes and biosensors. In parallel, the explosion of activity in nanoscience and nanotechnology and their huge success have profoundly affected biosensor technology, opening new avenues of research for electrode materials and transduction. This book provides an overview of biosensors based on amperometry, conductimetry, potentiometry, square-wave voltammetry, impedance, and electrochemiluminescence and describes the use of ultramicroelectrodes for the real-time monitoring and understanding of exocytosis. Areas of particular interest are the use of silver and gold nanoparticles for signal amplification, photocurrent transduction, and aptamer design. Moreover, advanced insights in the innovative concept of self-powered biosensors derived from biofuel cells are also discussed.

Summary : Biosensors are devices that detect the presence of microbials such as bacteria, viruses or a range biomolecules, including proteins, enzymes, DNA and RNA. For example, they are routinely applied for monitoring the glucose concentration in blood, quality analysis of fresh and waste water and for food control. Nanomaterials are ideal candidates for building sensor devces: where in just a few molecules can alter the properties so drastically that these changes may be easily detected by optical, electrical or chemical means. Recent advantages have radically increased the sensitivity of nanomaterial-based biosensors, making it possible to detect one particular molecule against a background of billions of others. Focusing on the materials suitable for biosensor applications, such as nanoparticles, quantum dots, meso- and nanoporous materials and nanotbues, this text enables the reader to prepare the respective nanomaterials for use in actual devices by appropriate functionalization, surface processing or directed self-assembly. The emphasis throughout is on electrochemical, optical and mechancial detection methods, leading to solutions for today's most challenging tasks. The result is a reference for researchers and developers, disseminating first-hand information on which nanomaterial is best suited to a particular application - and why.
