Research at the Division of Biotechnology
We are involved in several projects aiming at the development of cell-based biosensors for in vitro analysis. The research has the following directions:
Development of Organ-on-a-Chip devices for in vitro toxicity assaying and drúg testing.
The using patient specific cells derived from induced pluripotant stem cells (iPSC) where differentiated cells are used in 3D configurations in the biochip. The work is done together with partners in the IMI-EU StemBANCC project.

In collaboration with the Division of Industrial Production (IEI) at LiU we study the methodology for development and design of complex biotechnology instruments, devices and processes. The study also includes applications of stem cell manufacture and artificial organ bioreactors. The work has resulted in several publications including a new book where the biomechatronic methodology is decribed for a number of biotechnology applications. Read excerpts...

Soft sensors for bioprocesses
Methods for better monitoring and control of bioprocesses are studied with the purpose to enhance Process Analytical Technology (PAT) principles. Our approach is broader than PAT from the regulatory scope. PAT is expanded to cover bioprocesses in general (not only pheramceutical products) and economical and industrial aspects are purpsued. In particular we exploit the following methods:
Soft sensors Robust on-line sensors supported by mathematical models derived from the systems under study. Soft sensors are useful for bioprocess monitoring due to the complexity of the biological mechanisms of the producing cells. We have used software sensors to monitor physiological signals from typical industrial cultures by combining on-line sensors such as NIR, gas analyzers and HPLC for biomass, effluent gases and key metabolites with basic mass balance and kinetic equations.
Rational design of sensor and control systems By using systematic design principles (Biomechatromnics) sensor and control systems are design in a more rational way. The systematic design aims at finding the most efficient sensor and control configuaration for the process in relation to the the users goals, either economical, quality-related or else (see also separation project).
Operator Training Simulators The practial use of sensor systems in a bioprocess requires efficient training and education methods of production staff and bioengineers. This is done by creating a vitrual process environment on the training laboratory. Also here, systematic approaches provide significant improvements in training as already done within other areas (e.g. flight simulators).
