This work offers three solutions tailored to specific applications to overcome NMR challenges in the micro-domain. As the first sub-topic of this work, different potential electrode designs, compatible with NMR technique, are suggested and experimentally evaluated. As the second focus point, this work tackles multinuclear detection challenges. In parallel, a low-cost, broadband insert is discussed to enhance the sensitivity of standard NMR coils when a small sample volume is available.
This thesis presents a theoretical and experimental approach for the rapid fabrication, optimization and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. Developing non-invasive and reusable diagnostics sensors that can be easily manufactured will support the monitoring of high-risk individuals in any clinical or point-of-care setting. Sensor fabrication approaches outlined include silver-halide chemistry, laser ablation and photopolymerization. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. The sensors exhibited reversible Bragg peak shifts, and diffracted the spectrum of narrow-band light over the wavelength range λpeak ≈ 495-1100 nm. Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. Lastly, a generic smartphone application to quantify colorimetric tests was developed and tested for both Android and iOS operating systems. The sensing platform and smartphone application may have implications for the development of low-cost, reusable and equipment-free point-of-care diagnostic devices.
The goal of this book is to provide an introduction to the practical use of mobile NMR at a level as basic as the operation of a smart phone. Each description follows the same didactic pattern: introduction, basic theory, pulse sequences and parameters, beginners-level measurements, advanced-level measurements, and data processing. Nuclear Magnetic Resonance (NMR) spectroscopy is the most popular method for chemists to analyze molecular structures while Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool for medical doctors that provides high-contrast images of biological tissue depicting the brain function and the beating heart. In both applications large super-conducting magnets are employed which magnetize atomic nuclei of an object positioned inside the magnet. Their circulating motion is interrogated by radio-frequency waves. Depending on the operating mode, the frequency spectrum provides the chemist with molecular information, the medical doctor with anatomic images, while the materials scientist is interested in NMR relaxation parameters, which scale with material properties and determine the contrast in magnetic resonance images. Recent advances in magnet technology led to a variety of small permanent magnets, by which NMR spectra, images, and relaxation parameters can be measured with mobile and low-cost instruments.
In the next 10 to 15 years, chemical engineers have the potential to affect every aspect of American life and promote the scientific and industrial leadership of the United States. Frontiers in Chemical Engineering explores the opportunities available and gives a blueprint for turning a multitude of promising visions into realities. It also examines the likely changes in how chemical engineers will be educated and take their place in the profession, and presents new research opportunities.
In this book, the term "electrochemical nanotechnology" is defined as nanoprocessing by means of electrochemical techniques. This introductory book reviews the application of electrochemical nanotechnologies with the aim of understanding their wider applicability in evolving nanoindustries. These advances have impacted microelectronics, sensors, materials science, and corrosion science, generating new fields of research that promote interaction between biology, medicine, and microelectronics. This volume reviews nanotechnology applications in selected high technology areas with particular emphasis on advances in such areas. Chapters are classified under four different headings: Nanotechnology for energy devices - Nanotechnology for magnetic storage devices - Nanotechnology for bio-chip applications - Nanotechnology for MEMS/Packaging.
The objective of this book is to provide the fundamental comprehension of a broad range of topics in an integrated volume such that readership hailing from diverse disciplines can rapidly acquire the necessary background for applying it in pertinent research and development field.

This volume explores the different approaches and techniques used by researchers to study the recent challenges and developments in metabolic profiling. This book is divided into IV parts. Part I contains chapters that highlight basic concepts, such as experimental design, data treatment, metabolite identification, and harmonization. Part II describes experimental protocols for both targeted and untargeted metabolomics covering the basic analytical technologies: LC-MS, GC-MS, NMR and CE-MS. In addition the protocols describe methods for the study of tissues, feces, blood and other types of biological samples as well as the application of chemical derivatization for GC-MS. Parts III and IV present the use of metabolomics in the study of food, plants and the life sciences, with examples from the quest for the discovery of disease biomarkers, physical exercise omics and metabolic profiling of food, fruit and wine. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and thorough, Metabolic Profiling: Methods and Protocols is a valuable resource for researchers who are interested in expanding their knowledge of this rapidly developing field.
Contains approximately 800 alphabetical entries, prose essays on important topics, line illustrations, and black-and-white photographs.
The metabolism of all living organisms consists of elaborate and complex interactions among numbers of biomolecules, including protein-protein interactions. BIACORE is a new device that uses surface plasmon resonance for kinetic analysis of molecular interactions and automates whole analytical processes. The number of users of BIACORE is increasing worldwide, but until now nothing had been published in English to explain the principles of this new methodology and the kinds of applications it makes available. This updated and revised version of the Japanese original explains the underlying principles of BIACORE, providing concrete examples that utilize the methodology for analysis in areas ranging from basic to applied sciences. With its generous use of illustrations, this book is a valuable source of information for all users of BIACORE.
