| Abstract |
Pesticide has caused serious health implications to people and the environment even with a small amount. Surface-enhanced Raman scattering of gold and silver nanoparticle was a powerful analytical tool for the sensing of trace molecules.
We synthesized gold nanostar by one step seedless method at room temperature. This method iseasy, time- and energy-saving method and generated a rough and clean gold surface. Gold nanostars display tunable optical properties in the visible and near-infrared region which lead to a strong electromagnetic field enhancement. This has beenapplied to analyze trace pesticide at a small scale with high sensitivity and selectivity
