10:30 AM - BIOTECHNOLOGY DIVISION SEMINAR: The Optimization of DNA Microarrays From a Chemist's Perspective
The increased usefulness of DNA microarrays will depend on optimizing the chemical and physical properties of a glass slide and its ability for favorable DNA binding and hybridization on the surface. Commercial companies have focused on aminosilanes as their coating of choice because it easily binds to glass and possesses an amine functional group to effectively bind DNA via electrostatic interactions. Products using aminosilane coatings are a vast improvement over "in-house" poly-L-lysine slides that are prone to high background fluorescence and aging issues. However, aminosilane coatings degrade in ambient conditions. A different approach using functionalized multilayers which are electrostatically bound to the surface provides lower backgrounds and competitive signal/background ratios to commercial slides such as Corning GAPS II at a fraction of the cost. However, while explanations for the processes in microarrays can be fabricated with elaborate yet simplistic cartoons to match the experimental results, there is surprisingly little empirical evidence to back up the surface chemistry in the DNA microarray literature.

10:45 AM - MATERIALS AND CONSTRUCTION RESEARCH DIVISION SEMINAR: LADARs for Construction Site Metrology
Although LADAR technology has been around since the 1960s, the broad use of LADARs developed only within the last decade. This lag was due mainly to prohibitive costs and limited reliability of the early instruments. As the technology matured, however, costs of these instruments have been reduced and reliability has improved. The applications for LADARs are widespread and include 3D-modeling, automation, urban planning, mapping, surveying, autonomous vehicle navigation, quality control in manufacturing, global climate monitoring, bathymetry, and homeland security (face recognition, surveillance). The number of applications is seen to increase as technology improves and the size and cost of the LADARs continue to decrease. The presentation will give a general overview of the Construction Metrology and Automation Group’s (CMAG) efforts on the use of LADARs for the construction industry. These efforts include LADAR data processing, meshing, scan registration, terrain characterization, and performance evaluation of LADARs.

3:30 PM - SURF SUMMER SEMINAR SERIES: CSI Exists at NIST
Most criminal investigations today will involve or be assisted by some device or tool of technology. In general, to ensure a thorough investigation, law enforcement and forensic scientists must not be overwhelmed by the technology. NIST has been requested to assist with this concern by providing simple and novel solutions. Some of these solutions are in the form of Standard Reference Materials (SRMs), Reference Materials (RMs) or research into new methodologies. This presentation will provide a brief overview of some projects taking place at NIST to include a discussion on their need, their impact and their application to a high profile homicide case.

7/13/04 10:30 AM - NIST SEMINAR: Addressing Challenges for Hydrogen Storage and Fuel-Cell Development with Neutron Methods
The study of hydrogen in materials by neutron scattering and imaging methods is an important area of materials research. For example, such hydrogen-related studies can facilitate a deeper understanding of the fundamental properties underlying many of today's cutting-edge materials of relevance to fuel-cell and hydrogen-storage technologies, key components of any future hydrogen economy. For the most part, the great utility of neutron methods for advancing these types of technologies stems from the novel properties of the neutron and its interactions with matter, especially the different isotopes of hydrogen. The unusually large neutron scattering cross section for hydrogen (and deuterium) as well as the neutron's great penetrating power are routinely exploited in order to probe the amount, location, bonding states, and dynamics of hydrogen (and water) in a variety of technologically interesting materials. Developments over the past decade at the NIST Center for Neutron Research and elsewhere have greatly enhanced the sensitivity and dynamic range of neutron methods, and led to increasing interest by American industry and science in the use of neutron probes. This talk will provide a flavor of the capabilities of modern neutron instrumentation at NIST for the present and future energy systems and materials important for the hydrogen economy, from micron-scale imaging of working fuel-cell stacks and hydrogen-storage beds to molecular-scale characterization of hydrogen location, bonding, and transport mechanisms in fuel-cell membranes and hydrogen-storage materials.

7/14/04 10:00 AM - NIST SEMINAR: Nanoscale Self-Assemblies for Molecular Recognition
One of the areas of focus in our research group is the design, synthesis, and characterization of the molecular recognition efficacies of nanoscale self-assemblies. An overview of our research program and significant results from the following specific research areas will be presented in this seminar: (1) Design and synthesis of self-assembling acylpyrazolones and acylisoxazolones and their efficacies for the recognition of trivalent lanthanide metal ions. (2) Synthesis of acylpyrazolone tethered SiO2 nanoparticles and their self-assembling properties. (3) Synthesis of undoped and doped ZnS quantum dots, their emission and EPR spectroscopic properties, and ligand binding efficacies. (4) Nanoparticle-nanopolymer-nanomolecule-receptor (NNNR) motifs as luminescent sensors for a variety of target molecules such as biomolecules (prostaglandins), chemical warfare agents (the G series nerve gas agents) and biotoxins (bacteria and viruses). (5) Bioengineered bacterial flagella and the flagellin proteins as scaffolds for the construction of novel nanotubes for sensor applications. The underlying principle of self-assembly at the nanoscale for the generation of the various nanomaterials and their interactions at the molecular level leading to molecular recognition will be discussed.
