Abstract
This laboratory experiment is designed to give upper-level undergraduate students experience in nanotechnology by synthesizing and characterizing gold nanoparticles. The two-to-four week project begins with the synthesis of the ligand, 1,2-bis(diphenylphosphino)ethane (dppe). Students then use the dppe to prepare gold nanoparticles. The products are analyzed by IR and NMR spectroscopies and comparisons are made between the bound and unbound ligand. The gold nanoparticles are further characterized by UV–vis spectroscopy and transmission electron microscopy.
Supplement
The student handout and instructor notes, including comments on the experiment, additional results, grading criteria, equipment and reagent lists, and hazard alerts, are available.
