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

New Paper:
Taylor Expanding a Molecule on NEMS
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.    
New Paper:
Resonant Nanowires on Thick MEMS
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.
