(and silver) nanoparticles and nanostructures have unique physical and chemical
properties that have created new opportunities for biomedical applications in
diagnostics and therapeutics, and in optical and electronic materials.<SPAN
style="mso-spacerun: yes"> </SPAN>This talk will describe experimental and
theoretical research that has led to the synthesis and fabrication of unusual
gold and silver nanostructures, to their chemical functionalization, and to the
development of optical and other techniques for their use in practical
applications. One class of nanomaterial involves the use of DNA to functionalize
and link together gold nanoparticles to produce gel-like materials that have
found applications in both biological sensing and in the use of nucleic acids as
drugs. Here I emphasize a new class of superlattice crystalline material
constructed from DNA-linked gold particles that provides unique capabilities for
building complex structures that enable applications that combine plasmonics and
photonics.<SPAN style="mso-spacerun: yes"> </SPAN>Another class of
nanostructure involves aggregated gold and silver particles with very small
(<1nm) gaps.<SPAN style="mso-spacerun: yes"> </SPAN>Small gaps provide
opportunities for producing extremely high (>10<SUP>8</SUP>) enhancement
factors for surface enhanced Raman spectroscopy (SERS) studies.<SPAN
style="mso-spacerun: yes"> </SPAN>Here I describe recent applications to
single molecule and single particle SERS, as well as related work on
tip-enhanced Raman spectroscopy.<SPAN style="mso-spacerun: yes">
</SPAN>The use of theory to guide and interpret the experimental work is
emphasized throughout this talk.<B
