Seed-Mediated Synthesis of Branched Gold Nanocrystals Derived from the Side G…

We report the first synthesis of elongated penta-branched gold nanocrystals with a shape resembling that of a star fruit but with sharp ends by a seeding growth approach. Cetyltrimethylammonium bromide (CTAB) capping surfactant was used, and AgNO3 was added to the last growth solution to promote the formation of the five side branches. Through an investigation of the products collected by ad…
