Abstract

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.
