BIOLOGICAL APPLICATIONS OF MULTIPHOTON SCANNING NEAR FIELD OPTICAL MICROSCOPY

Vinod Subramaniam
Department of Molecular Biology, Max Planck Institute for Biophysical Chemistry. Gottingen, Germany


Thursday, February 18, 1999, 10:30AM, Rm. B165, Bldg 221.

We have implemented multiphoton excitation with continuous-wave (CW) and picosecond pulsed lasers in our scanning near-field optical microscope (SNOM). With a CW laser operating at 647 nm we can generate background-free images of the important near-UV absorbing DNA dyes Ethidium Bromide, DAPI, and Hoechst 33342 bound to polytene chromosomes and cell nuclei. Using a picosecond pulsed 1064 nm laser we can simultaneously image two-photon excited visible dyes and three-photon excited near-UV dyes in a crosstalk-free manner. Multiphoton excitation yields enhanced axial resolutions and improved photobleaching characteristics compared to one-photon excitation for our samples.

OXIDATIVE STRESS AND AGING

Richard Cutler
President and Scientific Director, Human Longevity Sciences. Phoenix, AZ


Thursday, February 18, 1999, 10:30AM, Lecture Room A, Administration Building.

Metabolism, like other aspects of life, involves tradeoffs. Scientists now know that oxidant by-products from normal metabolism and exogenous sources cause damage to DNA, protein and lipid (fat). This damage, known as Oxidative Stress, has been implicated in a range of diseases including cancer, arteriosclerosis, neurodegenerative diseases such as Parkinson's and Alzheimer's, and aging.

Antioxidant supplements protect your body from oxidative stress damage, but how does one know they are working. To answer this question, a new diagnostic field has emerged. Oxidative Stress Profiling analyzes key markers within your body to determine an individual's level of oxidative stress and level of antioxidant protection.

To learn about this exciting field, Dr. Richard G. Cutler will discuss the current measurement technologies used for analysis and outline the importance of monitoring one's level of oxidative stress.

Optical Technology Division Seminar

MORPHOLOGY AND LATERAL PATTERNING OF SUBSTRATE-SUPPORTED DIBLOCK COPOLYMER FILMS - THEORY AND EXPERIMENT

Michael J Fasolka
Department of Materials Science and Engineering, MIT.


Friday, February 19, 1999, 1:30PM, Rm. B165, Bldg 221.

The microphase separation behavior of diblock copolymers in thin films differs from that in the bulk due to the increased influence of surface boundary conditions. Surface effects are especially important in films that are thinner than the equilibrium period of the ordered copolymer. Here, the morphology is highly thickness dependent. Substrate supported films, (which are of technical and practical importance) are characterized by having highly asymmetric surface boundary conditions as the copolymer/substrate energetics most often differ greatly from that of the free surface. To better understand the behavior of supported diblock copolymer films, we have completed self-consistent field calculations which model these systems. Additionally, we have developed a technique using atomic force microscopy to experimentally probe film-thickness dependent diblock morphology. We have applied this technique to the study of sub-L thick films of polystyrene-b-poly(n-alkyl methacrylate) diblock copolymers on silicon substrates. The morphological trends illuminated by this study can be exploited via a novel and simple scheme to created laterally patterned thin films. Here, substrate topography is used to control the local copolymer domain orientation. The resulting films chemically reflect the substrate topography they overlay.

Advance Notice NIST Colloquium Series

USING SUPERCOMPUTERS TO DESIGN AND MODEL NOVEL MATERIALS

Professor Steven R. Richardson
Materials Science Research Center, Howard University.


Friday, February 19, 1999, 10:30AM, Green Auditorium, Administration Building.

Everyone is familiar with the marvelous computer simulations being used in the movies, like scenes of the Titanic sailing off from Liverpool, intergalactic space travel, and toys, ants, and pigs with anthropomorphic behavior. Professor Richardson will discuss how the power of modern supercomputers, coupled with recent advances in computational materials science and theoretical condensed matter physics, is enabling us to design and study novel materials -- new plastics, new composite materials, and new drugs -- and then model their behavior and test their performance under simulated conditions. As an example, he will discuss recent calculations on the structural properties of the energetic material, solid cubane, and a first-principles study of the high pressure phases of zinc.

AI PLANNING: A NEW APPROACH

Dana Nau
Prof., Computer Sciences & Dir., Computer-Integrated Manufacturing Laboratory, Univ. of Maryland.


Monday, February 22, 1999, 11:00AM, Lecture Room D, Administration Building.

The Simple Hierarchical Ordered Planner (SHOP) is among the fastest and most versatile systems for computational planning (often called artificial intelligence planning). In fact, it is proving to be orders of magnitude faster than other general planning methods. It is the outgrowth of work in planning that has also been applied to manufacturing planning and even incorporated in a successful electronic bridge-playing program that featured in stories in the New York Times and Washington Post. This talk summarizes recent experiences with the technique, as well as the possible future uses.

Biography: Dana Nau ( http://www.cs.umd.edu/users/nau/ ) is professor of Computer Science and Director of the Computer-Integrated Manufacturing Laboratory at the University of Maryland. His research interests include artificial intelligence in planning and searching and computer-integrated design and manufacturing. He received his Ph.D. from Duke University in 1979 and now has more than 200 technical publications. An NSF Graduate Fellow and later an NSF Presidential Young Investigator, he has also been awarded the ISR Outstanding Systems Engineering Faculty award at the University of Maryland, and is a Fellow of the American Association for Artificial Intelligence (AAAI).

NIST Colloquium Series

ANTI-ANGIOGENIC THERAPY OF EXPERIMENTAL CANCER

Judah Folkman
Director, Surgical Research Laboratory, Children's Hospital, Boston.


Friday, March 5, 1999, 10:30AM, Green Auditorium, Administration Bldg.

Anti-angiogenic drugs slow tumor growth by stopping the process of developing new blood vessels and interfering with the tumor's blood supply. Pioneering work by Dr. Folkman and collaborators has demonstrated that angiostatin and endostatin, when given together, make cancerous tumors disappear and not return. These new substances, fragments of larger and more common proteins found in blood vessels, were discovered being produced by a primary tumor and having the effect of inhibiting the growth of additional tumors. They do not act on tumors, but on normal blood vessels that feed them. It appears that the drugs act on all tumors, even leukemia, the same way, with virtually no side effects. This discovery has been called the single most exciting thing on the horizon for the treatment of cancer.

SELF-ORGANIZATION IN NONLINEAR OPTICS: DISCOVERY, DESIGN, AND APPLICATIONS

Dr. Mikhail Vorontsov
Army Research Laboratory.


Thursday, February 18, 1999, 7:45PM, First Floor Conference Room, OSA Headquarters, Washington, DC.

The variety of spatio-temporal phenomena that have been observed recently in coherent and nonlinear optics is one of the more striking features of modern optics today. These studies have resulted not only in a large variety of aesthetically attractive patterns and waves, but also in new and novel opportunities for information processing. The interaction between different nonlinear modes (patterns) occurs in the form of cooperative and competitive dynamics, and exhibits properties similar to those found in neural networks. The principle of Winner Takes All is as applicable to optical pattern formation as it is to biology, market economies and politics.

The more complex are the nonlinear system dynamics, the greater is the potential information capability of that system. The key questions are how to use this potential, and how to design and control complexity having the properties we desire. Vorontsov has been designing a kaleidoscope of spatial self-organization phenomena in nonlinear optics using a few rather simple building blocks, nonlinear optical systems with two-dimensional optical and electronic feedback circuits. He'll also discuss artificial complexity, or the complexity that arises not in nature but as a result of nonlinear interactions artificially created in optical systems.
