PreSens is developing a new sensor system
In cell culture experiments in bio- and gene technology and in biological and medical research a strong trend can be seen in the use of miniaturised approaches. The goal is the use of frequently very valuable media and cell cultures in the smallest possible volumes. This imposes very high demands on the surveillance of the actual state in the culture. The newly developed sensor system from the company PreSens with integrated optical sensors makes it possible to record continuously important biological parameters such as oxygen, pH and temperature in microbioreactors and disposable artificial vessels. In doing so it is also then possible to monitor the cultivation conditions in the smallest cultivation system and if necessary to correct these. An example of its use is a new measuring device, the so-called SensorDish Reader (SDR). This device makes it possible to measure two parameters at the same time. The apparatus uses sterile dish-like containers that are covered with a small sensor. A further advantage is in the simple and rapid ability to follow the cultivation of bacteria and cell cultures on the PC screen. The new technology of PreSens GmbH allows the determination of the parameters mentioned above without touching anything, works without requiring calibration and facilitates the parallel measurement of hundreds of containers. The company PreSens Precision Sensing GmbH was founded in 1997 by the University of Regensburg together with co-workers from the Max Planck Institute for Marine Microbiology in Bremen, and today has over 20 employees. The enterprise is financed by private funding and can already speak of net sales proceeds for all its R&D activities.
