A novel one-step in situ synthesis of gold nanostars (AuNSs) on a pre-cured polydimethylsiloxane (PDMS) film is proposed for the fabrication of highly sensitive surface-enhanced Raman scattering (SERS) substrates. Plasmonic activity of the substrates was investigated by collecting SERS maps of 4-mercaptobenzoic acid (4-MBA). The applicability of these flexible substrates is further demonstrated by SERS-based pesticide detection on fruit skin.
提出了一种在预固化聚二甲基硅氧烷（PDMS）薄膜上一步原位合成金纳米星（AuNSs）的新方法，用于制备高灵敏度表面增强拉曼散射（SERS）基底。通过收集4-巯基苯甲酸（4-MBA）的SERS图谱研究了基底的等离子体活性。基于SERS的水果表皮农药检测进一步证明了这些柔性基底的适用性。
