Research Interest
Nanowires and Nanotubes, Photonic Band Gap Fibers, Micro and Nanophotonics, Plasmonics, Sensors and Devices, Functional Surfaces, Photonic Nose

Research Overview
While the majority of chemical processes are no doubt driven by interactions between individual molecules, more complex structures, formed through the assembly of large molecular subunits, dominate the biological scape and display a number of curious properties. Dr. Akkaya’s group characterizes the behavior of such complex molecular assemblies and their interactions, with emphasis on the optical behaviors exhibited by fluorescent dyes. These molecules can be used as molecular sensors, solar cell sensitizer dyes, biological markers and therapeutic agents in photodynamic treatments.

Spectroscopy and Imaging Laboratory

Group Leader
Aykutlu Dana

Research Interest
Force Microscopy and Spectroscopy, Micro and Nano Electro-opto-mechanical System and Sensors, Plasmon Resonance Based Detection, Photovoltaic Materials and Devices

Research Overview
The rising field of plasmonics brings together light and metallic nanostructures to harness the benefits of electromagnetic modes of such nanostructures, and is highly conductive to useful applications in a number of fields, such as on-ship optical signal routing, biosensors and surface-enhanced Raman and infrared spectroscopies. The Spectroscopy and Imaging Laboratory focuses on the design and fabrication of plasmonic surfaces for biomolecular sensing down to the single-molecule level, potentially allowing the use of low cost optoelectronics, such as those present in contemporary mobile phones, for biomolecular sensing.
