该文采用处理后的泡沫镍为反应模板,直接还原氯金酸溶液,经实验条件优化,原位制备了纳米金-泡沫镍多孔磁性复合表面增强拉曼散射(SERS)基底(Au-NFs)。泡沫镍三维网状具有大的比表面积和粗糙度,可稳定负载纳米金,通过Au—S键化学吸附更多的目标分子6-巯基嘌呤。复合基底的磁特性易于磁分离富集,避免血液共存物对SERS检测6-巯基嘌呤的干扰。利用磁场诱导纳米金-泡沫镍聚集,可进一步优化纳米金局域等离子场分布,形成SERS热点,大大提升了分析灵敏度,对于探针分子4-巯基吡啶的检出限可达5×10

In this paper,porous magnetic gold nano-foam nickel composite is in situ prepared as surface enhanced Raman scattering(SERS) substrate(Au-NFs) by directly reducing chloric acid gold solution with treated foam nickel as a reductive reaction template. The three-dimensional network of foam nickel with a large specific surface area and roughness could tightly load gold nanoparticles and chemically adsorb more target molecules 6-mercaptopurine via the Au—S bond. The magnetic properties of the composite substrate make it easy for magnetic separation and enrichment to avoid the interference of blood coexistence species on SERS detection of 6-mercaptopurine. By using magnetic field,porous magnetic Au-NFs can be further optimized the distribution of the local plasma field of gold nanoparticles to form SERS hot spots,which greatly improve the detection sensitivity. For probe molecule 4-mercaptopyridine,the Au-NFs-based SERS detection limit at 5×10

mol/L could be reached. Under external magnetic field,with Au-NFs composite substrate,a linear detection of 6-mercaptopurine concentration locates in the range of 5×10

mol/L. Without sample pretreatment,this Au-NFs substrate could be used for rapid analysis of 6-mercaptopurine spiked in serum with recoveries ranging from 92.8% to 107%,indicating the reliability of the method.
