Like other noble metals, gold nanoparticles (AuNPs) have inherent optical properties that depend on their particle size, providing a variety of potential applications such as optical devices. Recently we have developed highly stable AuNPs complex encapsulated by the surfactant in aqueous solution. The coated AuNP is very stable for long time (＞ 3 months) and re-dispersible in aqueous solution after freeze-drying. Using this AuNP, we tried to fabricate highly ordered superlattice of AuNP by interacting with the amphiphilic molecules (F127, Brij58, etc). In this presentation, we report the result of the self-assembly of AuNP-amphiphilic molecules complexes by using small angle X-ray scattering.
