Branched plasmonic nanostructures have been found to exhibit strong enhancement of the electromagnetic field surrounding their multi-branched petals. This feature endows them with improved performance in catalysis, surface-enhanced Raman scattering, photoacoustic imaging, and photothermal therapy. Albeit several synthesis techniques have been developed, the precisely controlled growth of highly branched nanostructures with a one-pot surfactant-free procedure is still challenging. Herein, we present a simple seedless route to synthesize gold nanostars (AuNSs) using a natural plant polyphenol, gallic acid (GA), as a reducing and stabilizing agent. The size and shape of AuNSs can be tuned by simply adjusting the amount of added GA. Under the optimum condition, the as-prepared AuNSs with diameters about 100 nm exhibit strong near-infrared absorption, good photothermal efficiency, and high biocompatibility. We demonstrate that AuNSs can be utilized for simultaneous photoacoustic imaging and photothermal therapy in living cancer cells. This study highlights facile synthesized AuNSs could serve as a promising platform for cancer diagnosis and therapy.
