Measuring fluorescence-lifetime and bio-impedance sensors for cell based assays using a network analyzer integrated circuit.

Cell culture assays for therapeutic drug screening today are fully automated. Vitality of the cells is monitored by different sensors. For such a system, we propose a new reader unit, which is capable of reading two different fluorescent sensors and electrical impedance in 24-well-plates.

In-vivo cell and tissue monitoring with active implants.

Active implant systems are becoming increasingly important in modern medicine. We describe the development of an implantable system for the monitoring of dissolved oxygen. Tissue oxygen saturation plays a leading role in many pathophysiological processes in the human body such as the growth of malignant tumors or the viability of transplanted organs.
