    • Grating coupler integrated photodiodes for plasmon resonance based sensing 

      Turker, B.; Guner, H.; Ayas S.; Ekiz, O. O.; Acar, H.; Güler, Mustafa O.; Dâna, A. (Royal Society of Chemistry, 2011)
      In this work, we demonstrate an integrated sensor combining a grating-coupled plasmon resonance surface with a planar photodiode. Plasmon enhanced transmission is employed as a sensitive refractive index (RI) sensing ...

    • Resonant transmission of light through surface plasmon structures 

      Gurel, K.; Kaplan, B.; Guner, H.; Bayındır, Mehmet; Dana, A. (AIP Publishing, 2009)
      Plasmonics enables the realization of new optical components. Here, we report yet another plasmonic component based on a pair of surfaces displaying grating coupled plasmonenhanced transmission. We observe high quality ...

    • Sensitivity comparison of localized plasmon resonance structures and prism coupler 

      Kaya, Y.; Ayas S.; Topal, A. E.; Guner, H.; Dana, A. (2014)
      Plasmon resonances are widely used in biomolecular sensing and continue to be an active research field due to the rich variety of surface and measurement configurations, some of which exhibit down to single molecule level ...

    • A smartphone based surface plasmon resonance imaging (SPRi) platform for on-site biodetection 

      Guner, H.; Ozgur, E.; Kokturk, G.; Celik, M.; Esen, E.; Topal, A. E.; Ayas, S.; Uludag, Y.; Elbuken, C.; Dana, A. (Elsevier, 2017)
      We demonstrate a surface plasmon resonance imaging platform integrated with a smartphone to be used in the field with high-throughput biodetection. Inexpensive and disposable SPR substrates are produced by metal coating ...

    • Tuning optical discs for plasmonic applications 

      Kaplan, B.; Guner, H.; Senlik, O.; Gurel, K.; Bayındır, Mehmet; Dana, A. (Springer New York, 2009)
      We present simple physical and chemical procedures that allow tuning and modification of the topography of gratings present in optical storage discs into geometries optimal for grating coupled plasmon resonance excitation. ...
