    • Concentric ring structures as efficient SERS substrates 

      Cinel, N. A.; Cakmakyapan, S.; Ertas, G.; Özbay, Ekmel (Institute of Electrical and Electronics Engineers, 2013)
      Plasmonic nanopatterned structures that can work as highly efficient surface-enhanced Raman scattering (SERS) substrates are presented in this study. A 'coupled' concentric ring structure has been designed, fabricated, ...
    • Hyperspectral stochastic optical reconstruction Raman microscopy for label-free super-resolution imaging using surface enhanced Raman spectroscopy 

      Dana, Aykutlu (Springer, 2015)
      Super-resolution imaging is an emerging field that has attracted attention in the recent years due to far the reaching impact in biology. All super-resolution techniques use fluorescent labels to image nanoscale biomolecular ...
    • Plasmonic absorbers for multispectral and broadband absorption 

      Ayaş, Sencer; Güner, Hasan; Türker, Burak; Ekiz, Öner; Dana, Aykutlu (SPIE, 2012)
      We present polarization dependent multispectral and broadband plasmonic absorbers in the visible spectrum. The spectral characteristics of these structures are tunable over a broad spectrum. Experimental results are verified ...
    • Raman enhancement on a broadband meta-surface 

      Ayas S.; Güner, H.; Türker, B.; Ekiz, O. O.; Dirisaglik, F.; Okyay, Ali Kemal; Dâna, A. (American Chemical Society, 2012-07-30)
      Plasmonic metamaterials allow confinement of light to deep subwavelength dimensions, while allowing for the tailoring of dispersion and electromagnetic mode density to enhance specific photonic properties. Optical resonances ...
