Laboratory Methods in Dynamic Electroanalysis is a useful guide to introduce analytical chemists and scientists of related disciplines to the world of dynamic electroanalysis using simple and low-cost methods. The trend toward decentralization of analysis has made this fascinating field one of the fastest-growing branches of analytical chemistry. As electroanalytical devices have moved from conventional electrochemical cells (10-20 mL) to current cells (e.g. 5-50 mL) based on different materials such as paper or polymers that integrate thick- or thin-film electrodes, interesting strategies have emerged, such as the combination of microfluidic cells and biosensing or nanostructuration of electrodes. This book provides detailed, easy procedures for dynamic electroanalysis and covers the main trends in electrochemical cells and electrodes, including microfluidic electrodes, electrochemical detection in microchip electrophoresis, nanostructuration of electrodes, development of bio (enzymatic, immuno, and DNA) assays, paper-based electrodes, interdigitated array electrodes, multiplexed analysis, and combination with optics. Different strategies and techniques (amperometric, voltammetric, and impedimetric) are presented in a didactic, practice-based way, and a bibliography provides readers with additional sources of information. - Provides easy-to-implement experiments using low-cost, simple equipment - Includes laboratory methodologies that utilize both conventional designs and the latest trends in dynamic electroanalysis - Goes beyond the fundamentals covered in other books, focusing instead on practical applications of electroanalysis

Dairy foods account for a large portion of the Western diet, but due to the potential diversity of their sources, this food group often poses a challenge for food scientists and their research efforts. Bringing together the foremost minds in dairy research, Handbook of Dairy Foods Analysis, Second Edition, compiles the top dairy analysis techniques and methodologies from around the world into one well-organized volume. Exceptionally comprehensive in both its detailing of methods and the range of dairy products covered, this handbook includes tools for analyzing chemical and biochemical compounds and also bioactive peptides, prebiotics, and probiotics. It describes noninvasive chemical and physical sensors and starter cultures used in quality control. This second edition includes four brand-new chapters covering the analytical techniques and methodologies for determining bioactive peptides, preservatives, activity of endogenous enzymes, and sensory perception of dairy foods, and all other chapters have been adapted to recent research. All other chapters have been thoroughly updated. Key Features: Explains analytical tools available for the analysis of the chemistry and biochemistry of dairy foods Covers a variety of dairy foods including milk, cheese, butter, yogurt, and ice cream Analysis of nutritional quality includes prebiotics, probiotics, essential amino acids, bioactive peptides, and healthy vegetable-origin compounds Includes a series of chapters on analyzing sensory qualities, including color, texture, and flavor. Covering the gamut of dairy analysis techniques, th e book discusses current methods for the analysis of chemical and nutritional compounds, and the detection of microorganisms, allergens, contaminants, and/or other adulterations, including those of environmental origin or introduced during processing. Other methodologies used to evaluate color, texture, and flavor are also discussed. Written by an international panel of distinguished contributors under the editorial guidance of renowned authorities, Fidel Toldrá and Leo M.L. Nollet, this handbook is one of the few references that is completely devoted to dairy food analysis – an extremely valuable reference for those in the dairy research, processing, and manufacturing industries.

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

Electroanalytical chemistry, as the name implies, involves the analysis of chemical species through the use of electrochemical methods. Generally, alterations are measured in the concentration of a chemical species by measuring changes in current in response to an applied voltage with respect to time. According to Faraday's law, the charge is directly proportional to the amount of species undergoing a loss (oxidation) or gain (reduction) of electrons. Constant potential amperometry, high-speed chronoamperometry, fast cyclic voltammetry (FCV) and differential pulse voltammetry (DPV) are the most common voltammetric techniques used to detect monoamine neurotransmitters (ie, serotonin, dopamine, norepinephrine). Each method has its pros and cons. In constant potential amperometry, a uniform potential is applied and the change in current is monitored as a function of time. The advantage of this technique is that the time resolution is limited only by the data collection frequency of the instrument.
