Fluidic Manufacture of Star-Shaped Gold Nanoparticles

Star-shaped gold nanoparticles (StarAuNPs) are extremely attractive nanomaterials, characterized by localized surface plasmon resonance which could be potentially employed in a large number of applications. However, the lack of a reliable and reproducible synthetic protocols for the production of StarAuNPs is the major limitation to their spreading. For the first time, here we present a robust protocol to manufacture reproducible StarAuNPs by exploiting a fluidic approach. Star-shaped AuNPs have been synthesized by means of a seed-less protocol, employing ascorbic acid as reducing agent at room temperature. Moreover, the versatility of the bench-top microfluidic protocol has been exploited to afford hydrophilic, hydrophobic and solid-supported engineered StarAuNPs, by avoiding intermediate NP purifications. Stars in-flow: Anisotropic star-shaped gold nanoparticles are synthesized by exploiting a microfluidic process. The seed-less and user-friendly protocol afforded highly reproducible and morphologically controlled nanoparticles. Moreover, different surface-engineered nanoparticles can be obtained while avoiding time-consuming purification steps.
