The focus of this theme is on the development of microfluidic systems for (bio)-medical applications, thereby increasing the knowledge of biological systems and improving the diagnostics and treatment of diseases. Microfluidics are a perfect tool for this, since dimensions comparable to single cells are used, low sample volumes are needed and multiple functionalities can be integrated in one platform. As an example electrodes can be integrated in in these devices, making electrical measurements on single cells such as sperm cells, or a tissue layer like the blood-brain barrier possible. By carefully analyzing these electrical signals, information about the morphology of the sperm cell or tightness of the tissue layer can be retrieved, which can be used to gain information about the semen quality or the functioning of the blood-brain barrier. Additional useful information can be retrieved form (automated) optical analysis using for instance fluorescence or bright field microscopy. So using these and other (new) techniques in combination with microfluidics, biomedical microdevices are developed that can finally be of use in the clinic. There are collaborations with other research groups at this and other universities, but also with doctors at the hospital, making it an applied multidisciplinary research area.
