    • Metamaterial-based wireless strain sensors 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Puttlitz, C.; Demir, Hilmi Volkan (American Institute of Physics, 2009-07-07)
      We proposed and demonstrated metamaterial-based strain sensors that are highly sensitive to mechanical deformation. Their resonance frequency shift is correlated with the surface strain of our test material and the strain ...
    • Observation of defect formation in metamaterials 

      Çağlayan, Hümeyra; Bulu, I.; Loncar, M.; Özbay, Ekmel (OSA, 2008-10)
      We report subwavelength localization of electromagnetic fields within cavities based on metamaterials. Cavity resonances are observed in the transmission spectrum of a split ring resonator and composite metamaterials cavity ...
    • Real-time and selective detection of single nucleotide DNA mutations using surface engineered microtoroids 

      Toren, P.; Ozgur E.; Bayındır, Mehmet (American Chemical Society, 2015)
      Mictoroids, as optical biosensors, can provide beneficial biosensing platforms to understand DNA alterations. These alterations could have significant clinical importance, such as the case of Pseudomonas aeruginosa, which ...
    • Ultrasensitive label-free microcavity biosensors with high selectivity 

      Özgür, Erol; Bayındır, Mehmet; Aktaş, Ozan (IEEE, 2011)
      High quality factor whispering gallery mode microresonators have been recently shown to exhibit detection sensitivity of single molecule; however, the selectivity of these sensors among different types of analytes remains ...
