Breast cancer cell lines detection by a microwave resonant sensor

In the last years, the measurement of materials’ dielectric properties has become a central issue for their impact on scientific research, such as for industrial, communication and environmental applications. Recently, various systems based on microwave biosensing achieved great benefits in healthcare and biomedical fields due to their minimal invasiveness, high versatility, and sensitivity. In addition, microwave sensors are able to measure living tissues dielectric properties through non-invasive scattering parameters. Changes in these factors, which are strictly related to the resonant frequency of the probe, could be crucial for monitoring or diagnosing possible pathological states. For example, the early detection of tumours is a critical part of cancer research for reducing the mortality rate. However, due to the complex and various signaling pathways involved in cancer development, there is a lack of knowledge on tumor behavior.
