A multicomponent nanostructure comprising of gold nanorod-nanoparticle (AuNR-AuNP) composites was fabricated to detect thrombin at subnanomolar concentrations in diluted human blood serum. Simulation and experiments revealed that the strong electromagnetic coupling resonance at the nanorod-nanoparticle junction of these probes can be used to construct highly sensitive SERS aptasensors.
一种由金纳米棒-纳米颗粒(AuNR-AuNP)复合材料组成的多组分纳米结构被制备用于在稀释的人血清中检测亚纳摩尔浓度的凝血酶。模拟和实验表明,这些探针在纳米棒-纳米颗粒连接处的强电磁耦合共振可用于构建高灵敏度的 SERS 适体传感器。
