Popis:	Various lipid-water systems, such as vesicles and microemulsions, have been used to produce nanoscale metal particles. These particles have potential applications in catalysis, micro- and nanoelectronics, magnetic recording, and optics depending on the metal and on the size and distribution of the formed particles. In this communication, we demonstrate for the first time the possibility of utilizing the bicontinuous cubic-phase structure of a lipid-water system to produce controlled-size metal nanoparticles with minimal polydispersity. The results show that the narrow aqueous channels of the bicontinuous cubic phase constrain the size of the metal particles, and therefore the cubic phase could provide a viable matrix for the synthesis of nanoscale materials. We have utilized a polyol-type process to reduce the palladium ions to metallic palladium. 9 refs., 2 figs.
