Abstract

A three-step seed-mediated growth method was used to make gold nanoparticles. Different surfactants, alkyltrimethylammonium bromides (C n TAB, n = 10, 12, 14, 16, and 18) and cetylpyridinium chloride (C 16 PC), were chosen as stabilizers. In general, it was found that as the length of the surfactant...
