GERMANY • The development of new vaccines is expensive and lengthy. So far, biosensors for monitoring the cell development in a cost-efficient and reliable way did not exist.
As part of the research project “Biography”, Saueressig is working on a method to print graphene colour and proteins on a substrate in order to provide the breeding ground and measuring device for the cells.
Besides Saueressig, the companies Haydale, cellasys and AiCuris as well as the Fraunhofer Institute IBMT participating in the interdisciplinary research team. Saueressig provides input for the development of the printing processes and the structuring of the printing tools.
The company argues that due to their directly engraved rotogravure printing rollers and their printing machine “Free-1” that was developed specifically for this purpose, electrically conductive and biocompatible graphenes could be printed on first substrates.
Free-1 is a printing machine that was originally developed for rotogravure and flexo printing. It compromises a gravure and flexo printing mechanism as well as a drying unit. Saueressig intends to print complete sensors in the near future.
According to its developers, one advantage of the new biosensors is the possibility of online monitoring within the protected environment of the incubator. The “Biography Biosensors” can be used in cell biology, virology or biosensorics.
