For the automation of processes, the use of microfluidic workflows is a flexible and powerful solution. Here, especially for analytical and diagnostic issues, the smart and appropriate sample handling is of great importance for the process result.

In recent years, we at Fraunhofer IMM have generated a wealth of expertise in integrating process steps such as sample collection, sample introduction, sample preparation and reagent supply into microfluidic workflows and have demonstrated this expertise using a wide range of application examples.

Microfluidics offers suitable possibilities for process steps such as mixing, diluting, incubating, lysing, fractionating and staining and can thus realize a wide range of tasks. Whether industrial media, environmental samples or human sample material, we at Fraunhofer IMM have the necessary knowledge and equipment to provide these media on microfluidic cartridges in the necessary quality for various analyses.
