　　Recently, syntheses of unique Au microcrystals using nonionic Brij surfactants, which are used as reducing, capping, and structure directing agents, have been reported by our research group.Triangular or hexagonal crystalline Au microrings were synthesized using a Aun+ precursor and nonionic Brij35 ((C2H4O)23C12H25OH) surfactant in aqueous solution.Hexagonal multilayered Au spirangles were also synthesized in a controllable fashion and in high yields, through a simple process in Brij 700 ((C2H4O)100C18H37OH) aqueous solution.
