April 2004 Meeting

Speaker:  Professor Richard P. Van Duyne
Charles E. and Emma Morrison Professor of Chemistry
Northwestern University
Topic: Nanoparticle Optics for Surface-Enhanced Sensing and Spectroscopy
Date: Friday, April 23, 2004
Location: The Parthenon Restaurant
(in the new banquet room)
314 South Halsted Street
Chicago, IL

Abstract:     During the last few years, there has been an explosion of interest and activity in the field of nanoparticle optics.  This talk will discuss the fabrication of size-tunable, well-ordered, 2D nanoparticle arrays using nanosphere lithography (NSL) and electron-beam lithography (EBL).  Nanosphere lithography (NSL) is an inexpensive, simple to implement, inherently parallel, high throughput, materials general nanofabrication technique capable of producing an unexpectedly large variety of nanoparticle structures.  Electron-beam lithography (EBL) is a standard, serial, nanofabrication technique capable to producing arbitrary nanostructures.  In addition, recent developments in the chemical synthesis of size and shape controlled noble metal nanoparticles will be discussed.  The use of localized surface plasmon resonance (LSPR) spectroscopy to probe the size-tunable optical properties of Ag nanoparticles and their sensitivity to the local, external dielectric environment (viz., the nanoenvironment) is discussed in detail.   In particular, the effects of molecular adsorbates on the LSPR spectrum of Ag nanoparticles are presented.  Applications to surface-enhanced Raman spectroscopy (SERS) and nanoscale optical chemo/biosensors will be given.

Biography:     Richard P. Van Duyne is Charles E. and Emma H. Morrison Professor of Chemistry at Northwestern University.   He is the discoverer of surface-enhanced Raman spectroscopy (SERS) and inventor of nanosphere lithography (NSL).  His research interests include surface-enhanced spectroscopy, nanofabrication, nanoparticle optics, combined scanning probe microscopy/Raman microscopy, Raman spectroscopy of mass-selected clusters, ultrahigh vacuum surface science, structure and function of biomolecules on surfaces, and surface-enhanced spectroscopic methods for chemical and biological sensing.  Professor Van Duyne is the recipient of several awards

Immediately following dinner---

A meeting of the Chicago Section JOB CLUB will be held at the Parthenon at 5 PM. The JOB CLUB provides a continuing opportunity for unemployed members of the Section to meet one another, share their experiences and develop a network that may help in identifying employment opportunities. Bring plenty of resumes and business cards to distribute to your colleagues. A presentation of some of the primary resources that are useful for conducting a job search will be made.

Should you wish to attend the Section meeting following the JOB CLUB, the fee for unemployed members is only $14 and you can continue your networking activities over dinner.

Topical Group Presentation

There will be an Undergraduate Research Symposim at 5:00 PM presented by students of Mark Walters from Oakton Community College. The speakers will be: Martin Parker, Stephen Kim and Shivani Shah.

Shivani Shah Fungal Diversity from Oakwood Lands
Stephen Kim

Job Club: 5:00 - 6:00 PM
Topical Group Meeting: 5:00 - 6:00 PM
Social Hour: 6:00 PM - 7:00 PM
Dinner: 7:00 PM
Meeting: 8:00 PM
