Speaker: Assoc. Prof. Alpan Bek, Middle East Technical University

Topic: "High Resolution Optical Microscopy and Spectroscopy Techniques in Biology"

Location: Middle East Technical University, Ankara, Turkey (EEE Sevim Tan)

Abstract:  High resolution optical microscopy and spectroscopy used to be limited in the micrometer spatial resolution for about 3 centuries after development of the first microscopes in 17th century. The limiting factor behind such a long time of further advancement has ultimately  been the diffraction limit of visible light. It was in late 20th century when technology has finally advanced beyond the limitation of diffraction to enable optical spatial resolution down to the nanometer. Nanometer dimension is the realm of large molecules of which maybe most interesting ones such as proteins are of biological origin. In this talk I will present the ideas behind breaking the diffraction limit and give an overview of several high resolution imaging and spectroscopy techniques in biological specimen analysis.

Bio:  Alpan Bek has completed his BSc and MSc studies at Bilkent University Department of Physics. He has taken part in experimental research on optical properties of low dimensional systems and integrated optics under supervision of Prof. Atilla Aydinli. He has obtained his PhD degree from Ecole Polytechnique Federale de Lausanne (EPFL) while he conducted his PhD work at the Max-Planck Institute for Solid State Research in Stuttgart, Germany under supervision of Prof. Klaus Kern. He has constructed an optical microscope that can resolve structures down to 5 nm with visible light. He has had a post-doctoral stay at Ludwig Maximillian’s University of Munich (LMU) in the group of Prof. Jochen Feldmann and conducted research together with Prof. Thomas Klar on plasmonic systems. Afterwards he has moved to Cluster in Biomedicine (CBM) in Trieste, Italy to work together with Dr. Marco Lazzarino on tip enhanced Raman spectroscopy (TERS). In 2011 he has returned back to Turkey as a faculty member in Physics Department of Middle East Technical University. He is currently conducting research in the fields of plasmonic solar cells and nonlinear plasmonics as the leader of the Nano-Optics Research Group and as a member of The Center for Solar Energy Research and Applications (GÜNAM).
