A surface acoustic wave sensor for detection of cell adhesion

In this paper preliminary results for the detection of the cell adhesion process with shear-horizontal polarized surface acoustic wave devices (SH-SAW) are presented. The murine fibroblast cell line L929 was investigated. Therefore a special measurement setup was developed. It enables us to perform long term measurements at stable ambient conditions. Different amounts of cells where seeded. According to the number of cells different slopes of resonant frequency increase vs. time were found.
