Radical Ring-Opening Polymerisation
Synthesising a polyester from a radical polymerisation has some interesting features compared to a classic ring-opening polymerisation. The radical feature now allows for functional groups like amines. Since the final structure is still a polyester, it can by hydrolysed and can also be biodegraded using esterase. Altogether, this polymerisation does hold some very compelling features but also some tough challanges which we will conquer along the way.
It is somewhat of an age-old question of polymer chemstry: How can we apply the vast array of polymers with all their functionalities for a certain application. Within the RTG “Hydrogel-Based Microsystems” with the TU Dresden, we apply this onto hydrogels and their use in microfluidics. Our hydrogels tend to hold responsive units (e.g. from complexation) as responsive additional cross-linking points.

It is fair to say that we have a bit of a history in the field. Amphiphilic block-copolymers can self-assembly into a large array of structures, but we find the polymersomes most compelling. With their aqueous core and hydrophobic part of the membrane, they can host hydrophilic and hydrophobic cargo. If a molecule contains both domains, like protein, it can even host these ones in their membrane. A lot has been seen and done on these vesicles, but as they say: There is loads of room at the bottom!
