WORKSHOP: Nanoscience on the Tip Location: Workshop
costs are covered by NUE UNIQUE, a NSF sponsored undergraduate program.
Travel and accommodation for MRSEC students outside the UW are sponsored by
GEMSEC. Application is closed for 2008. Objective and Background The objective of this intensive SPM workshop is to provide
a truly hands-on experience (3-4 students per instruments) in a classroom
laboratory setting involving a variety of SPM techniques applied to
nanoscience and nanotechnology aspects related to chemistry, physics and
biology. Since the
invention of the scanning tunneling microscope (STM) in 1981 by Gerd Binnig
and Heinrich Rohrer (Nobel Prize in Physics 1986) scanning probe microscopy
(SPM) techniques have dazzled scientist and engineers in nearly every field
from natural sciences to liberal arts, and nucleated the new discipline of
Nanoscience and Nanotechnology. The birth of such a highly interdisciplinary
field is an attest to the changing times in a world that moves from educating
specialists to generalists. The true power of SPM techniques, which assisted
in removing boundaries between disciplines, lays in its simplicity to provide
access to nanoworld in terms of visualization and manipulation. Hence, it is only
perceivable that SPM offers outstanding educational tools for schools. Synopsis and List of Laboratory Units Students will gain hands-on experience involving a wide variety of nanotechnology/nanoscience applications, using some of the most versatile nano-tools based on Scanning Probe Microscopy (SPM). With an intensive one-week schedule and a low student to instrument and student to TA ratio of 4:1, deep and lasting learning will occur. The intense 40 hours one-week workshop will provide students with the opportunity to apply their theoretical knowledge from prior lecture courses. Laboratory
Units (developed for 2007 and 2008 Workshop) Lab Unit I: Scanning Force Microscopy and
Dip-Pen Nanolithography The student
will become familiar with contact mode Scanning Force Microscopy (SFM) as an
imaging technique, and be introduced with Dip-Pen Nanolithography (DPN). Lab Unit IB: Introduction to Scanning Force
Microscopy The
student will become familiar with contact mode Scanning Force Microscopy
(SFM) as an imaging technique and as ultra-sensitive force sensor. Lab Unit II: AC-Mode imaging and Electrostatic Force
Microscopy This lab
unit introduces Electrostatic Force Microscopy to characterize the electrical
properties of a blended conjugated polymer film by studying the changes in
tip oscillation due to electrostatic force gradients between the tip and the
sample. Lab Unit
IIB: Binding
Kinetics of Proteins In his lab unit students are
characterizing protein-material using intermittent non-contact (NC) scanning
force microscopy (SFM) in both fluid medium and in air to quantify surface
adsorption. The material analyzed are graphite adsorbed blood clotting proteins, fibrinogen (Fb),
to mimic a bio-response to prosthetic heart valve devices. Lab Unit III: Force Spectroscopy Analysis This lab
unit introduces a scanning force microscopy (SFM) based force displacement
(FD) technique, FD analysis, to
study local adhesion, elastic properties, and force interactions between
materials. Lab Unit IV:
Force Modulation Microscopy This lab
unit introduces a scanning force microscopy (SFM) based mechanical
(sinusoidal) perturbation method referred to as force modulation microscopy,
to explore thermomechanical properties in polymers around the glass
transition. Lab Unit V:
Scanning Tunneling Microscopy This lab unit introduces scanning tunneling microscopy (STM) technique, used to obtain real space atomic resolution images of conductive surfaces. The tunneling spectroscopy mode of STM is employed to examine local density of state (LDOS) of the surface. List Lab Units under Constructions: In this unit, students will be introduced
to nanocomposites and the challenges involved in establishing material phase
contrast with AFM. AFM and transmission electron microscopy will be employed
to analyze materials. Educational
outcomes: Familiarize students with nanocomposite materials and their
potential in generating unique properties, such as reversed selectivity in
membranes. Lab Unit: Molecular Mobility and Organic
Electronics Students will be introduced to organic
electronics and exposed to the challenges involved in non-linear optical
organic polymer materials used for photonic applications. The aim is to
achieve effective device performance by utilizing submolecular
relaxations. Educational outcomes: The students will learn about molecular
mobility in polymers, the concept of the widely used superposition principle,
and an AFM based method. Instructors Prof. David Ginger (Chemistry) research focuses on the creation and
study of nanostructured materials with unique optoelectronic and photonic
properties. His group has pioneered novel
scanning probe microscopy and lithography methods to further our
understanding of nanostructured organic solar cells. His group is also developing bioinspired
assembly strategies for controlling near-field electromagnetic coupling
between fluorophores and plasmon resonant nanoparticles. Ginger is also known
for his work in the development of semiconductor nanocrystals for
photovoltaics and LEDs, and as a pioneer of Dip-Pen Nanolithography methods
for biomolecules. In recognition of
his research and education efforts he has been named a Research Corporation
Cottrell Scholar. Prof. René M Overney (Chem. Prof. Mehmet Sarikaya (Mat. Sci.) is known for his pioneering efforts and
ideas in Molecular Biomimetics. By
merging recent advances in molecular biology and genetics with
state-of-the-art engineering and nanocharacterization from the physical
sciences, his and his collaborators’ goal is to shift the biomimetic
materials science paradigm from imitating Nature to designing materials to
perform artificial nanofunctions. It is the intent to combine Nature’s proven
molecular tools, such as proteins, with synthetic nanoscale constructs to
make molecular biomimetics a full-fledged methodology. To this end, at the
Genetically Engineered Materials Science and Eligibility Requirement To be
eligible for the program you must be: 1. UG
