Metabolite Monitoring


The detection of small biological molecules represents an important task in bioprocess control –however, after decades of research and development the field still struggles with irreproducibilities, sensor drifts and instabilities of receptors.




Bioprocess engineering


Bioreactors are used in multiple ways. For example for the production of food or materials used to build power plants for renewable engergy, for bioengineering or by pharmaceutical industry. The number of installed bioreactors grows with an annual rate of more than 10%.



Korrodierter Bio-Halbleiterkontakt

The surfaces of processed semiconductors become unstable when exposed to bio milieus. In particular, aqueous solutions of electrolytes may easily cause corrosion of inorganic surfaces like Si, SiO2, SiON. Also biological materials degrade upon contact, for which the denaturation of proteins on Si/SiO2 surfaces is a well-known example.






The locally controlled immobilization of biomolecules on semiconductor surfaces will play a central role in future bioelectronics devices. Inscribing 3D structures into microchips is performed nowadays by a combination of thin film deposition and selective removal via photolithography and etching procedures.
