Rapid synthesis of hierarchical, flower-like Ag microstructures with a Gemini surfactant directing agent for SERS applications

Abstract

A simple and repeatable method to synthesize uniformly sized shape-specific nanomaterials is essential for fundamental studies and practical applications. In this article, novel and highly monodispersed hierarchical, porous, flower-like Ag microstructures (HFAMs) were fabricated only in a few seconds via a one-step reduction process at ambient temperature. The Gemini surfactant dodecanediyl-1,12-bis(dimethylhexadecylammonium bromide) (16-12-16) was used as the directing agent instead of conventional stabilizers, and showed excellent shaping abilities. Meanwhile, a series of hierarchical, monodispersed Ag microstructures, with great potential application value was obtained by adjusting the concentrations of various reagents. Also, the formation mechanism of HFAMs was proposed. Surface-enhanced Raman scattering (SERS) measurements showed the HFAMs can serve as extremely sensitive SERS substrates. This work further investigated the applications of these monodispersed microstructures and the importance of Gemini surfactants in controlling micro-nanomaterial shapes.
