In the Laboratory
From the Research Bench to the Teaching Laboratory: Gold Nanoparticle Layering
Maria Oliver-Hoyo and Ralph W. Gerber
Department of Chemistry, North Carolina State University, Raleigh, NC 27695
Cover
July 2007
Vol. 84 No. 7
p. 1174
Abstract
The emphasis currently being placed on research and development of nanotechnology strongly supports the introduction of nanoscience techniques and methodology into the undergraduate chemistry laboratory curriculum. The procedures presented within are designed for undergraduate chemistry students to experiment with synthetic, mechanistic, and measurable properties of gold nanoparticles and layering techniques. Methodology involves the synthesis of gold colloidal suspensions, attachment of a functional group to glass with subsequent creation of self-assembled monolayers (SAMS) through deposition of gold nanoparticles, and measurements of wavelengths, absorbance, and conductivity. Educational emphasis includes an understanding of the nanoscale and an exposure to nanotechnology through the synthesis and layering of gold nanoparticles.
Supplement
Experimental details, materials, equipment, and solution preparation instructions are available. Testing and experimentation used in the modification of the procedures for cleaning, silanation, layering, storage, and chemical usage are also included.
