  • Title: Controllable and reproducible construction of a SERS substrate and its sensing applications.
    Author: Wen Y, Wang W, Zhang Z, Xu L, Du H, Zhang X, Song Y.
    Journal: Nanoscale; 2013 Jan 21; 5(2):523-6. PubMed ID: 23223828.
    Abstract:
    A simple method for the preparation of a highly stable and reliable surface-enhanced Raman scattering (SERS) substrate was proposed. The SERS enhancement was demonstrated with good controllability and reproducibility through the controlled formation/deformation of SERS "hotspots" using a reversible DNA nanoswitch. Highly effective DNA detection was achieved using a well-designed sandwich structure.
