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.

Through this monograph, the pharmaceutical chemist gets familiar with the possibilities electroanalytical methods offer for validated analyses of drug compounds and pharmaceuticals. The presentation focuses on the techniques most frequently used in practical applications, particularly voltammetry and polarography. The authors present the information in such a way that the reader can judge whether the application of such techniques offers advantages for solving a particular analytical problem. Basics of individual electroanalytical techniques are outlined using as simple language as possible, with a minimum of mathematical apparatus. For each electroanalytical technique, the physical and chemical processes as well as the instrumentation are described. The authors also cover procedures for the identification of electroactive groups and the chemical and electrochemical processes involved. Understanding the principles of such processes is essential for finding optimum analytical conditions in the most reliable way. Added to this is the validation of such analytical procedures. A particularly valuable feature of this book are extensive tables listing numerous validated examples of practical applications. Various Indices according to the drug type, the electroactive group and the type of method as well as a subject and author index are also provided for easy reference.
