A copper nanoparticles@porous biocarbon substrate was designed for Surface-Enhanced Raman Spectroscopy (SERS) via a simple reduction method. In the detection of three trace antibiotics, the substrate exhibits a very high Raman enhancement efficiency. This is partly because the biocarbon is rich in meso-micropores, which can rapidly trap target molecules. On the other hand, the copper nanoparticles embedded on the surface of the carbon sheets generate a large number of plasmonic hotspots, leading to an increase in Raman signal intensity. These results suggest that this substrate has utility for SERS applications in food safety, medicine, and water pollution detection.
通过一种简单的还原方法设计了一种用于表面增强拉曼光谱（SERS）的铜纳米颗粒@多孔生物碳基底。在检测三种痕量抗生素时，该基底表现出非常高的拉曼增强效率。这部分是因为生物碳富含中微孔，能够快速捕获目标分子。另一方面，嵌入在碳片表面的铜纳米颗粒产生大量的等离子体热点，导致拉曼信号强度增加。这些结果表明，该基底在食品安全、医学和水污染检测的SERS应用中具有实用性。
