NMC 2018 conference
Our group had two talks in the NMC 2018 conference in Korea. Arda Secme presented our work on multimode microwave sensors for cell size and position determination.
Mert Yuksel talked about our multimode mechanical resonators for different sensing applications.
Visit of Prof. Anja Boisen
We had the pleasure of hosting Prof. Anja Boisen from DTU in our department's Distinguished Seminar Series. She gave a fantastic talk on micro-containers for drug delivery, as well as, several sensor technologies for lab-on-a-disc platform.
We have mapped out the relationship between the Taylor Expansion of a molecule's shape around its center and the corresponding multimodal response it induces on a NEMS resonator. We have exploited this relationship to reverse calculate the spatial properties and reconstruct the inertial image of an analyte. The paper has the title: Mass Spectrometry Using Nanomechanical Systems: Beyond the Point-Mass Approximation. It has been published in NanoLetters. The work has been done in collaboration with John Sader (University of Melbourne and Caltech) who lead the research, as well as Adam Neumann and Michael Roukes at Caltech.
We have detected the resonance motion of thin nanowires embedded in a much thicker MEMS structure. The paper has been published in the Journal of Micromechanics & Microengineering. The work has been done in collaboration with the Leblebici group at EPFL and the Alaca group at the Koç University.
New Paper: Microave Imaging Lab on a Chip
Our article, Towards Microwave Imaging of Cells, has been accepted for publication in the journal Lab on a Chip. You can reach it by clicking here.
In the paper, we show how to obtain cell size and location in a microfluidic system by exciting and measuring two modes of a microwave resonator.
Congratulations to our microwave team on their truly collaborative effort: Mehmet Kelleci, Hande Aydoğmuş, Levent Aslanbaş and Selçuk Erbil.

New Paper: Multidomain Model for NEMS
Prof. Alper Demir has developed a general framework which can analyze NEMS oscillators by combining the lumped elements for the circuit components and the distributed nature of mechanical vibrations (and delay lines) in the same model. Phase noise analysis for the combined NEMS oscillator model is also performed. This paper titled Numerical Analysis of Multi-Domain Systems: Coupled Nonlinear PDEs & DAEs with Noise will be published in IEEE TCAD and early access preprint is available on the IEEE website.
Arxiv Preprint - Mode Shape Perturbation
Mert Yuksel and Dr. Hanay have a new preprint on calculating deviations from the ideal mode shapes of a NEMS resonator due to the adsorption of analytes. The preprint is available on the Arxiv server. This work also has implications for the negative effects of surface roughness for multimode sensing. We are grateful for the support of European Commission FP7 Marie Curie Program.
