摘要：

This paper presents an innovative biosensing technique based on the interaction between biomaterial and microwave electromagnetic (EM) waves, which probes the bioparameters of investigated biological samples. Thanks to microtechnologies, this approach is able to sense biomaterials down to living cells size without invasivity. Broadband dielectric spectroscopy of living cells suspension is consequently demonstrated sketching a rich EM signature. Capacitive contrasts of 4% and 12% between cells suspension and pure medium are measured at 20 and 40GHz respectively. This analyzing technique consequently represents a promising integrated solution compatible with Lab-on-Chip (LoC) applications.
