Screening Platforms Based on Droplet Microfluidics and Towards Artificial Cells and Networks - NCCR MSE

Screening Platforms Based on Droplet Microfluidics and Towards Artificial Cells and Networks

The focus of our research is the development of microfluidic methods for applications in the life sciences.

In this project, we pursue three aims: i) The creation of small biochemical reactors (“artificial cells”) and ii) networks in the sense of molecular factories, and iii) the development of high-throughput, label-free screening methods with improved analytical readout. In all approaches, we use droplet microfluidics as the basic technology for the creation of controlled nL-volumes. Our system can be employed for a wide range of applications and adapted to many assays, which are developed by other groups in the NCCR.
