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.
