This book focuses on the basic electrochemical applications of DNA in various areas, from basic principles to the most recent discoveries. The book comprises theoretical and experimental analysis of various properties of nucleic acids, research methods, and some promising applications. The topics discussed in the book include electrochemical detection of DNA hybridization based on latex/gold nanoparticle and nanotubes; nanomaterial-based electrochemical DNA detection; electrochemical detection of microorganism-based DNA biosensors; gold nanoparticle-based electrochemical DNA biosensors; electrochemical detection of the aptamer-target interaction; nanoparticle-induced catalysis for DNA biosensing; basic terms regarding electrochemical DNA (nucleic acids) biosensors; screen-printed electrodes for electrochemical DNA detection; application of field-effect transistors to label free electrical DNA biosensor arrays; and electrochemical detection of nucleic acids using branched DNA amplifiers.

This book provides a broad introduction to all major aspects of quantum dot properties including fluorescence, electrochemical, photochemical and electroluminescence. Such properties have been produced for applications in biosensing, cell tracking, in vivo animal imaging and so on. It focuses on their special applications in DNA biosensing and provides readers with detailed information on the preparation and functionalization of quantum dots and the fabrication of DNA biosensors, using examples to show how these properties can be used in DNA biosensor design and the advantages of quantum dots in DNA biosensing. Further new emerging quantum dots such as metal nanoclusters and graphene dots and their applications in DNA biosensing have also been included.

Quantum dots (QDs) are hybrid organic/inorganic nanoparticles with novel physical properties. QDs have two components: an inorganic core and an optically active coated shell. Moreover, surface coatings can be applied to QDs 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, antibodies, 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 QDs have already been used in many applications, such as imaging probes for the engineering of multifunctional nanodevices. Superior properties of QDs make them an excellent system in technology and biotechnology.This book describes electroanalytical applications of QD-based nanobiosensors, including brief information about the synthesis and characterization of QDs and basics of electroanalytical methods, followed by QDs in electrochemical biomimetic sensors, QDs in microchips, inorganic materials doped QDs, QD-based electrochemical DNA biosensors, electroluminescence for biomarker analysis using aptamer-based QDs, QD-based photoelectrochemical techniques, enzyme-based nanobiosensors using QDs, QD-based electrochemical immunosensors, and QD-modified nanosensors in drug analysis. - Outlines QD-based applications for drug, food, clinical, and environmental science - Shows how the properties of QDs make them effective ingredients in biosensing applications - Assesses the major challenges in integrating QDs in biosensing systems
