{"abstract":[{"lang":"eng","text":"Experimental results of contactless and label-free characterization techniques of cell cultivation are presented. The two demonstrated approaches are compared at two frequencies, 7 GHz and 240 GHz in terms of sensitivity and applicability. At 7 GHz, measurements have been performed using a rat-race based characterizing system. Furthermore, the sensitivity of spectroscopy measurements at 240 GHz has been compared for two extracted parameters: phase and amplitude. The conducted experiments demonstrate that by selecting the proper characterization parameter, the presented techniques are suitable for cell cultivation monitoring in a pipe based microfluidic system with PTFE tubes. Especially, the use of higher frequencies enables a higher compactness."}],"type":"conference","date_created":"2025-06-27T11:24:17Z","doi":"10.1109/RWS.2013.6486703","status":"public","_id":"5995","citation":{"bibtex":"@inproceedings{Wessel_Schmalz_Cahill_Gastrock_Meliani_2013, title={Contactless characterization of yeast cell cultivation at 7 GHz and 240 GHz}, DOI={<a href=\"https://doi.org/10.1109/RWS.2013.6486703\">10.1109/RWS.2013.6486703</a>}, booktitle={2013 IEEE Radio and Wireless Symposium}, publisher={IEEE}, author={Wessel, Jan and Schmalz, Klaus and Cahill, Brian and Gastrock, Gunter and Meliani, Chafik}, editor={Institute of Electrical and Electronics Engineers (IEEE)Editor}, year={2013}, pages={247–249} }","apa":"Wessel, J., Schmalz, K., Cahill, B., Gastrock, G., &#38; Meliani, C.
