  • Title: SERS aptasensor from nanorod-nanoparticle junction for protein detection.
    Author: Wang Y, Lee K, Irudayaraj J.
    Journal: Chem Commun (Camb); 2010 Jan 28; 46(4):613-5. PubMed ID: 20062879.
    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.
