This additional degree of freedom has been used to design novel devices; the most prominent ones are Organic Light-Emitting Diodes, but Organic Photovoltaics and Organic Sensors are highly promising fields as well.</p> <p>We study the use of organic semiconductors in organic biosensors. Our research focuses on Organic Electrochemical Transistors, which reach high signal gains and can be processed at low costs. We study different approaches to functionalize these transistors and develop new processes to integrate organic sensors into larger systems and to interface them with conventional electronics.</p> <p>Organic sensors and sensor systems show high promise in several commercial applications. In particular the flexible nature of organic semiconductors enables the design of wearable sensor systems. Furthermore, the bio-compatibility of most materials can be used to form a strong link between organic devices and biological matter, which is in particular promising for the field of intra-body networks.</p> Content content-380602 Thu, 05 Mar 2026 17:02:07 +0100 https://www.uni-bremen.de/en/imsas#c380602 <p class="bodytext">The group investigates new approaches for miniaturized measurement systems for fluids. These systems are based on the concept of Physical Chemosensing: the determination of (bio)chemical concentrations or properties using physical measurement principles, which yields long term stability and straightforward fabrication compared to other methods. The applications range from life sciences to industrial liquids. The microfluidic chips are designed and realized in-house (<abbr title="Institut für Mikrosensoren, -aktoren und -systeme">IMSAS</abbr>-<abbr title="Microsystems Center Bremen">MCB</abbr>).</p> <p>Our multidisciplinary research is conducted in cooperation with partners from biotechnology, hospitals, and industry. The group coordinates the Marie Curie Initial Training Network (<abbr title="Initial Training Network">ITN</abbr>) EngCaBra in which engineering methods for the analysis of cancer and brain diseases are investigated. Current research topics are medical- and biochips, cell analysis, microfluidics and optofluidics, integrated sensors and sensor technology.</p> Content
