Abstract

Urchin-like gold nanoparticles (ULGNs) exhibit rich surface plasmon optical properties especially in Surface-enhanced Raman Scattering (SERS) due to their tunable branch number and length. In this work, ULGNs with hollow structure and tunable branches were successfully prepared by the one-pot method. By controlling its morphology, we found the number and length of branches increased with the increase of ascorbic acid. The size of nanoparticles and number of branches decreased with the increase of silver nitrate. To get better SERS activity, we prepared silver coated ULGNs (ULGNs@Ag). When the ULGNs@Ag branches were partially exposed beyond the silver layer, it shows the best SERS properties and we used it as a SERS substrate to complete the detection of malachite green. The linear detection range is from 10⁻⁸-10⁻³ mol·L⁻¹, and the detection limit is 2.5 nmol·L⁻¹, suggesting this research developed a new approach to food safety testing.
