CellTool was founded in 2008 by serial entrepreneurs Karin and Raimund Schütze in order to make photonic technologies available for biomedical applications. Based on their pioneering work and in close collaboration with leading experts across the disciplines – physics, biology, medicine and informatics – CellTool develops fully integrated systems that are easy to use and broadly applicable. These allow, for the first time, biological specimens to be identified, analysed and sorted without biochemical markers, fluorescent labels, antibodies or beads. As a result, cells remain untouched and vital, and can be subjected to further tests or manipulations as desired. Potential applications range from stem cell and cancer research to drug development, quality control and clinical practice.


CellTool closely collaborates with partners from academia, clinic and industry across many disciplinesto evaluate and further optimize the BioRam® system for different applications. As part of this strategy, the company has recently established a dedicated service laboratory providing space and equipment for third parties to testanalyse their samples with CellTool’s BioRam®system and explore potential applications, together with the company’s experts. Combining Raman Spectroscopy with biomedical applicationsIn close collaboration with scientists at the Fraunhofer Institute for Interfacial Engineering andBiotechnology, CellTool has overcome the particular technical challenges that have so far hampered routine use of Raman spectroscopy in biomedical research and development. Biological samples often emit fluorescence which interferes with their weak Raman signals. Furthermore, they require a tolerable wavelength and appropriate physiological conditions during measurement to preserve cell viability. BioRam®is the first integrated, robust and easy-to-use system that overcomes all these challenges.
