  • Development and Characterization of an Atmospheric Pressure Ionization Source Matrix-Assisted Laser Desorption Electrospray Ioni
    ABSTRACT SAMPSON, JASON SCOTT. Development and Characterization of an Atmospheric Pressure Ionization Source Matrix-Assisted Laser Desorption Electrospray Ionization Coupled to Fourier Transform Ion Cyclotron Resonance Mass Spectrometry for Analysis of Biological Macromolecules. (Under the direction of David Charles Muddiman). The field of mass spectrometry has grown tremendously over the past few decades due in large part to the continued application to new and interesting areas of exploration. The advent of soft ionization sources such as electrospray ionization and matrix-assisted laser desorption/ionization has dramatically increased the applications of mass spectrometry; in particular, analysis of complex biological samples. Electrospray ionization has demonstrated the capability to generate multiply-charged ions which increases the amount of information garnered from each analysis. Matrix-assisted laser desorption/ionization has demonstrated complex sample analysis requiring minimal sample preparation, which results in high throughput. As a result of these findings, there has been tremendous growth in the development of new ionization source technology in recent years for reducing sample preparation required prior to analysis for high throughput sample analysis and the generation of multiply-charged ions. Demonstrated herein is the development and characterization of an atmospheric pressure ionization source called matrix-assisted laser desorption electrospray ionization (MALDESI). MALDESI is a hybrid combination of MALDI and ESI which utilizes laser desorption with electrospray postionization for the generation of multiply-charged ions. Multiply-charged ions are of particular importance when using Fourier transform mass spectrometry, due to the increase in resolving power and mass accuracy with increasing charge on the molecule. Positive identification of biological macromolecules is demonstrated utilizing top-down characterization of intact polypeptides as well as high mass accuracy utilizing internal calibration.

  • Chapter 20 SOFT LASER DESORPTION IONIZATION - MALDI, DIOS and NANOSTRUCTURES
    Chapter 20 SOFT LASER DESORPTION IONIZATION - MALDI, DIOS AND NANOSTRUCTURES Akos Veites Department of Chemistry, Institute for Proteomics Technology and Applications, The George Washington University, Washington DC 20052 1. INTRODUCTION In 1948, Ame Tiselius won the Nobel Prize in chemistry for the discovery of electrophoresis and its application to analyze large molecules, specifically complex serum proteins. During the following decades, gel electrophoresis and its derivative techniques became a central method for molecular biology. They allowed for the identification of molecular mass with an accuracy of ~1 kDa, i.e., a thousand atomic mass units. Although this method enabled the separation of thousands of proteins from biological samples, the determination of the actual molecular weight, and with it finding the true identity of many substances, remained unachievable. When it came to accurate mass determination of small molecules, mass spectrometry was the method of choice. However, for the accurate mass analysis of large molecules, their low volatility presented a fundamental obstacle. Typically, the larger the molecule, the harder it is to transfer it into the gas phase without degradation. Depositing the energy necessary for volatilization initiates other competing processes that elevate the internal energy of the adsorbate and results in its fragmentation. This competition between evaporation (or desorption) and fragmentation was recognized early on and the method of rapid heating was proposed to minimize the latter (Beuhler, et al., 1974). Lasers with submicrosecond pulse length were appealing tools for rapid heating but the initial results indicated limitations with respect to the ultimate size of the biomolecules (m/z < 1,500) that could 506 Laser Ablation and its Applications be successfully analyzed (Posthumus ,et al., 1978).

  • Surface Modification and Laser Pulse Length Effects on Internal Energy Transfer in DIOS
    24450 J. Phys. Chem. B 2005, 109, 24450-24456 Surface Modification and Laser Pulse Length Effects on Internal Energy Transfer in DIOS Guanghong Luo,† Yong Chen,† Gary Siuzdak,‡ and Akos Vertes*,† Department of Chemistry, Institute for Proteomics Technology and Applications, The George Washington UniVersity, Washington, D.C. 20052, and Center for Mass Spectrometry, The Department of Molecular Biology, The Scripps Research Institute, La Jolla, California 92037 ReceiVed: August 3, 2005; In Final Form: October 5, 2005 Benzyl-substituted benzylpyridinium (BP) chloride salts were used as a source of thermometer ions to probe the internal energy (IE) transfer in desorption/ionization on porous silicon (DIOS). To modify their wetting properties and the interaction energies with the thermometer ions, the DIOS surfaces were silylated to produce trimethylsilyl- (TMS), amine- (NH2), perfluoroalkyl- (PFA), and perfluorophenyl-derivatized (PFP) surfaces. Two laser sourcessa nitrogen laser with pulse length of 4 ns and a mode locked 3 × ω Nd:YAG laser with a pulse length of 22 psswere utilized to induce desorption/ionization and fragmentation at various laser fluence levels. The corresponding survival yields were determined as indicators of the IE transfer and the IE distributions were extracted. In most cases, with increasing the laser fluence in a broad range (∼20 mJ/cm2), no change in IE transfer was observed. For ns excitation, this was in remarkable contrast with MALDI, where increasing the laser fluence resulted in sharply (within ∼5 mJ/cm2) declining survival yields. Derivatization of the porous silicon surface did not affect the survival yields significantly but had a discernible effect on the threshold fluence for ion production.

    FOREWORD This abstract booklet provides a record of the 2006 U.S. Department of Energy (DOE) Analysis Contractors’ Meeting. The objective of this meeting is to provide a fruitful environment in which researchers with common interests will present and exchange information about their activities, will build collaborations among research groups with mutually reinforcing strengths, will identify needs of the research community, and will focus on opportunities for future research directions. The agenda has keynote talks, oral presentations, and posters; with ample time for discussion and interactions, we emphasize that this is an informal meeting for exchange of information and building of collaborations; it is not a review of researchers’ achievements or a forum to choose future directions. We are pleased to have the privilege of organizing this joint meeting and of serving as the managers for the research program. In carrying out these tasks, we learn from the achievements and share the excitement of the research of the many sponsored scientists and students whose names appear on the papers in the following pages. We also hope that this meeting will enhance your research efforts and will nurture future collaborations and initiatives. We thank all of the researchers whose dedication and innovation have advanced our research and made this meeting possible and, we hope, productive. We hope that all of you will build on your successes and that we will assemble in a very few years for our next meeting. We thank Diane Marceau of the Chemical Sciences, Geosciences and Biosciences Division, and Sophia Kitts and Angie Lester of the Oak Ridge Institute for Science and Education for the technical and logistical features of this meeting.

Laureates John B. Fenn, Koichi Tanaka (MS) and Kurt Wüthrich (NMR) have pioneered the successful application of their techniques to biological macromolecules. Biological macromolecules are the main actors in the makeup of life whether expressed in prospering diversity or in threatening disease. To understand biology and medicine at molecular level where the identity, functional cha- racteristics, structural architecture and specifc interactions of biomolecules are the basis of life, we need to visua- lize the activity and interplay of large macromolecules such as proteins. To study, or analyse, the protein molecules, principles for their separation and determination of their individual characteristics had to be developed. Two of the most important chemical techniques used today for the analysis of biomolecules are mass spectrometry (MS) and nuclear magnetic resonance (NMR), the subjects of this year’s Nobel Prize award. Mass spectrometry (MS) The ability to separate molecules based on different size and charge was frst described in 1912 by J.J. Thompson (Nobel Prize laureate in 1906 for investigations of the conduction of electricity by gases) and expressed as the mass/charge ratio with the unit Thompson (Th).
