If we can make life-like chemical systems with signal-processing regulatory networks, then we should have outstanding opportunities to establish communication with cells and their signaling networks to cross-regulate behavior, which can ultimately lead to biohybrid morphogenesis.

Funded by our new ERC Consolidator Grant, we will establish this research line within our newly built cell lab.

Together with partners, we already target a more immediate application of for instance for 3D printed nanocellulose materials, for which we could show excellent biocompatibility, as well as possibilities for cell-friendly degradation to make free standing 3D cell constructs or possibly allow in vivo degradation. Additionally, we engage in cancer immunotherapy within the SFB 1066 together with a range of partners at JGU Mainz and the University Clinic.
