Spring '18 Department Seminars with Dr. Serap Aksu
Title: “Seeing” the Proteins in the Infrared by Plasmo-Fluidics
Speaker: Dr. Serap Aksu
Department of Physics, Bilkent University
Date: April 10, 2018, Tuesday
Place: Departmental Seminar Room (SB-Z14)
Plasmonics enables us to detect biological molecules even in extremely minute amounts using subwavelength light confinement and enhancement near metallic surfaces. Coupled with microfluidics, these detection techniques can lead to powerful methods to quantify molecules in situ and in real time. In this talk I will elaborate on design and fabrication of plasmonic biosensors and their applications in conventional vibrational spectroscopy. I will also introduce a novel plasmo-fluidic platform to quantify the secretion of cell signaling molecules in a high-throughput manner using the case of single immune cells as an example. These microfluidic devices are based on membrane valve technology and thus are fully automated, and allow measurements in parallel. The quantitative understanding of biological cell signaling using novel systems is fastly developing and the presented device provides a competent approach for accurate modeling of immune functions.
