Abstract :
A millimeter-wave sensor based on a CPW line has been designed and fabricated as a first prototype for impedance spectroscopy to be combined with a multifunctional micropipette for cell and membrane analysis. The first mm-wave measurement results show the sensitivity of the layout by distinguishing the cells from the media and monitoring the attachment process of the cells to the sensor surface. Measurements were performed on umbilical cord stem cells and cartilage thumb cells.
