โฆ Synopsis
This overview summarises the use of surface-active agents for preparation of nanoparticles. It starts with description of the nanotechnology vision. Nanoparticle products are exemplified by using solid-state processes, e.g. for the production of ceramics or catalysts, as well as colloidal processes whereby the use of surface-active agents plays a major role. Several examples are given in the review, e.g. use of coordination ligands and nanoparticle selfassembly. The process of control of nanoparticle shape and its modulation is briefly described and examples are given to demonstrate such control.

Copper nanoparticles protected by self-assembled monolayers of decanethiol have been prepared by the controlled reduction of aqueous copper salts using the modified Brust synthesis. For comparison, the nanoparticles are synthesized on different concentration of cetyltrimethylammonium bromide (CTAB).
