A method of making nanocrystals involves adding a chalocogen source to a hot solution of a metal-containing non-organometallic compound, such as CdO, in a first ligand solvent, such as TOP, and preferably subsequently cooling the resulting mixture to a lower temperature to grow the nanocrystals at said lower temperature. The method can involve either one ligand or two-ligand systems.

Method of synthesizing colloidal nanocrystals

A combined process is described in which inclusion complexes are formed from guest molecules and cyclodextrins during agglomeration of the cyclodextrins. Sufficient agitation in the presence of a small amount of water results in complex formation and bonding into strong agglomerates. The agglomerates are strong and stable and useful inter alia in foods (the guest molecules are flavors), pharmaceuticals (the guest molecules are drugs) and agriculture (the guest molecules are various agrochemicals).
