Book Description
This book covers the state-of-the-art of modern MALDI (matrix-assisted laser desorption/ionization) and its applications. New applications and improvements in the MALDI field such as biotyping, clinical diagnosis, forensic imaging, and ESI-like ion production are covered in detail. Additional topics include MS imaging, biotyping/speciation and large-scale, high-speed MS sample profiling, new methods based on MALDI or MALDI-like sample preparations, and the advantages of ESI to MALDI MS analysis. This is an ideal book for graduate students and researchers in the field of bioanalytical sciences. This book also: • Showcases new techniques and applications in MALDI MS • Demonstrates how MALDI is preferable to ESI (electrospray ionization) • Illustrates the pros and cons associated with biomarker discovery studies in clinical proteomics and the various application areas, such as cancer proteomics

Book Description
This book presents innovative laser desorption ionization (LDI)-active nanophotonic structures for addressing the challenges that matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) is currently facing and for enhancing LDI efficiency. It presents a variety of cutting-edge nanophotonic structures to satisfy the mass-analytical needs of sensitivity, reproducibility, and quantification. As opposed to the commercialized, conventional organic matrix used in MALDI-MS, these nanostructures are validated to be highly effective in detecting small metabolites and drugs, highlighting their considerable potential in the mass spectrometry field. It also systematically elucidates fundamental LDI processes in terms of the photo-thermal, electronic, and structural characteristics of nanophotonic structures, offering mechanistic knowledge of LDI-MS. Even though LDI-MS performance is heavily influenced by a number of nanostructure parameters, relatively little is known about the LDI processes associated with those characteristics. An in-depth understanding of nanostructure characteristics and LDI mechanisms thus paves the way for more effective, rational design and development of nanostructures with improved LDI capabilities. Further, with a focus on multiple cascades in nanostructure functions in response to laser pulse stimuli, this book provides detailed, step-by-step procedures to design and construct a nanophotonic, LDI-active platform, which may serve as a roadmap for graduate students in the field of mass spectrometry. Readers, including graduate students, researchers, and experts working in the related areas of mass spectrometry, nanophotonics, and material science and material engineering, will find a wealth of useful information in this book.

Book Description
Endogenous biomolecules, such as neuropeptide, protein and carbohydrates, play important roles in biological and physiological processes. Over the last two decades, therapeutic biomolecules, including therapeutic peptides, proteins and monoclonal antibodies, have become large and fast-growing segments of the pharmaceutical industry. However, analyzing biomolecules is challenging due to their large size, complex structure and various modifications. In situ analysis of biomolecules is even more challenging due to the large dynamic range and complex microenvironments on tissue surface. In this dissertation, matrix-assisted laser desorption/ionization (MALDI) and liquid chromatography (LC) -- electrospray ionization (ESI) based mass spectrometric techniques were developed to characterize and quantify endogenous and therapeutic biomolecules. Specifically, this work developed novel ionization techniques and mass spectrometry imaging workflows to study the sequence and in situ distribution of biomolecules on high resolution accurate mass instrument platforms. Moreover, absolute or relative quantifications of biomolecules, such as therapeutic peptide or N-glycans, were measured by cutting-edge quantification workflows. In summary, this work not only improves current analytical methodology for characterizing biomolecules, but also demonstrates its potential applications in pharmaceutical industry and clinical settings.
