通过银镜反应和巯基表面功能化制备了超疏水银膜。巯基功能化显著提高了Ag膜的疏水性能（AFS），其接触角值随着巯基烷基链的延伸而略有增加，达到约160度。研究了这些膜的表面增强拉曼散射（Sers）检测能力，AFS-Dodcc是检测R6 G分子的最佳基底，其浓度极限为10（-11）M。将十二烷基硫醇功能化的原子荧光光谱（AFS-Dodec）用于尿酸和肌酐的表面增强拉曼光谱（Sers）检测，在5 ~ 1000 μ M的浓度范围内，拉曼强度与分析物浓度呈良好的线性关系。(C)根据OSA开放获取出版协议的条款，2018年美国光学学会
Superhydrophobic silver films were fabricated by silver-mirror reaction and surface functionalization with thiol. The thiol-functionalization significantly improved the hydrophobic property of the Ag films (AFS), and their contact angle values slightly increased with the extension of a thiol alkyl chain, reaching about 160 degrees. The surface-enhanced Raman scattering (SERS) detection capacity of these films were investigated, and AFS-Dodcc showed the best substrate for R6G molecule detection with the concentration limit of 10(-11) M. AFS functionalized with dodecanethiol (AFS-Dodec) was applied for the SERS detection of uric acid and creatinine, it exhibited good linear dependence relationship between the Raman intensity and analyte concentration in the concentration range of 5 similar to 1000 mu M.
