Once penetrating inside biological cells, microwaves can interact with their intracellular content and inform on their safe or malignant state. This work demonstrates that their cancer grade (i.e. aggressiveness level) can also be identified by this way. Hence, based on permittivity measurements on three colon cancer cell lines loading RF resonators, the presented results show significant differences of electromagnetic signature in the cancer grade of analyzed cells. This sensing method appears very promising to develop new powerful tools for early cancer diagnostic. %G English %L hal-00923028 %U https://unilim.hal.science/hal-00923028 %~ UNILIM %~ CNRS %~ XLIM %~ XLIM-MINACOM %~ EA3842 %~ GEIST %~ CAPTUR %~ OMEGAHEALTH
