US Patent 7138098 - Nanocrystal Fabrication without Organometallic Reagents

Nanocrystal fabrication techniques include pyrolysis (high heat transformation) of organometallic reagents. Unfortunately such reagents can be costly, dangerous, and difficult to handle. This patent from M.I.T. teaches an alternative methodology that does not require such reagents. Claim 1 reads:

1. A method of manufacturing a nanocrystal comprising heating a mixture including a coordinating solvent, an amine or a reducing agent, a chalcogen or pnictide source, and a metal-containing compound to form a nanocrystal, wherein the metal-containing compound is free of metal-carbon bonds.
