Microphysiological Systems

Real-Time Monitored Organ-on-Chip Systems for Personalized Drug Development

We develop microphysiological systems, such as organ-on-chip platforms, that are flexible and thus customizable – providing a sustainable alternative to animal testing. With integrated real-time monitoring, we precisely analyze cell viability and the metabolic activity of various cell models, including tissues, spheroids, and organoids.

Our systems enable dynamic, stable short- and long-term studies to evaluate the efficacy and safety of drugs, cosmetics, and chemicals (REACH). Compared to conventional endpoint measurements, they provide direct access to mechanism-of-action analyses, thereby optimizing therapy screening and the development of combination therapies.

With our customizable microphysiological systems, we are shaping the future of preclinical drug development and personalized oncology.

SkinMonitor: Microfluidic System Platform

Based on full-skin models for sensor-monitored real-time analyses

Microfluidic lab-on-a-chip system for sensor-based investigation of skin cell models (skin-on-a-chip)

In collaboration with Fraunhofer IGB, we developed a test system for the investigation of cosmetic substances on skin models (skin-on-chip). For this purpose, 3D in vitro full skin models (Fraunhofer IGB) were linked via a microfluidic system with cell- and sensor-based analytics (Fraunhofer IZI-BB). The integration of optical oxygen sensors enables real-time analytics of cell viability, while reporter cells of the IGB indicate, for example, interleukin expression or activation of sensitizing signaling pathways. This combination enables the collection of detailed data on the toxicity of test substances.

Microfluidic bioreactors for in-vitro toxicity measurements (Liver-on-a-Chip)

The microphysiological system (liver-on-a-chip) developed in this project for assessing the long-term toxicity of active compounds is intended to replace animal testing in the medium term. Real-time measurements of parameters such as glucose and oxygen concentrations and pH levels enable both quality control of the culture conditions and the acquisition of valuable time-resolved information on the metabolic activity of hepatocytes when they are exposed to drug candidates or chemical substances.
