2013 TÜBA-GEBİP Member Assoc. Prof. Gökhan Demirel and 2015 TÜBA-GEBİP Member Assoc. Prof. Hakan Usta made an important breakthrough by demonstrating for the first time that nanostructured, superhydrophobic organic semiconducting films can be used in the SERS field.

Demirel and Usta said that they are proud of publishing these important results of this two-year intensive work on “Nanostructured organic semiconductor films for molecular detection with surface-enhanced Raman spectroscopy” in Nature Materials Journal, one of the most prestigious material journals in the world and that the basic financial support was provided by TÜBA-GEBIP.

Gazi University Department of Chemistry Faculty Member Assoc. Prof. Gökhan Demirel and Abdullah Gül University Department of Material Sciences and Nanotechnology Engineering Faculty Member Assoc. Prof. Hakan Usta succeeded in growing n-type organic semiconductors, α, ω-diperfluorohexylquaterthiophene (DFH-4T) molecules in a 3-dimensional and nanostructured manner with a unique manufacturing approach. They showed that the produced structures could provide unique enhancement without any plasmonic coating in SERS applications. This was the first time in the world that SERS was able to provide strengthening of an organic-based structure, despite the use of metallic and inorganic structures. The result of theoretical calculations contributed by one of the authors of the article Yavuz Dede, 2014 TÜBA-GEBİP Member and Gazi University Department of Chemistry Faculty Member, shows that the mechanism of this unique enhancement observed in experiments is not only load-transfer based but also plays a fundamental role in 3-dimensional morphology.

In the report that he wrote to the Natural Materials Journal, The City University of New York (CUNY) Department of Chemistry Faculty Member Prof. John R. Lombardi said that “The work will open up new horizons in the SERS field, and this discovery will increase the use of SERS in the field of molecular sensors in the near future.”
