Smart Stimuli-Responsive Polymer Membranes

  • Cascade reactions in nanoreactors acting in tandem.
    Cascade reactions in nanoreactors acting in tandem.

Contrary to the macroscopic world, the engineering of integrated systems at molecular level imposes a complex scenario of requirements, especially for assembling biotic and abiotic components with the dual aim; to preserve the specific functionality of each entity, and to induce new functionalities and properties serving a final desired application.

A variety of molecular entities such as membranes, self-adapting vesicles, and biological molecules (enzymes, proteins, mimics) were used to design protein-polymer supramolecular assemblies with new functionality and improved stability. For example, nanometer size compartments that contain active compounds in their inner structures can increase the safety and efficacy of polymerization reactions and catalysis, offer protected space for cascade reactions, serve as “on demand” sources for reactive oxygen species, or provide multifunctionality as artificial organelles.

Collaborations with project groups with competences in polymer chemistry, inorganic chemistry, molecular biology, metabolic engineering and characterization methods for complex systems/reactions for a complete design and characterization of hybrid systems will be essential in the first years of this project.

The aim of this project group is to extend these activities towards development of stimuli-responsive assemblies that are hierarchically self-organized into clusters and networks with the goals of designing: i) Complex functional architectures for cascade reactions, and ii) Hybrid bio-synthetic membranes with responsive and self-adapting properties. Later, these protein-polymer clusters/networks will be integrated in complex systems with multifunctionality and controlled responsiveness to support the development of molecular factories.
