We propose a research and innovation project that aims to develop a rational, knowledge-based toolbox for the fabrication of (1) biodegradable and biocompatible associating (gel-forming) polymers, (2) nanogels and (3) nanoparticles tailored as multifunctional therapeutic agents in ophthalmological applications. We seek for novel methods to replace currently used approaches with biocompatible and biodegradable synthetic/natural polymers. Macromolecules of increasingly complex architectures including block, graft and star-like polymers will be explored with respect to their ability to build up transient networks or nanoparticles with well-controlled rheological and structural properties and targeted performance. Profound understanding of the relation between architectural complexity and properties of the macromolecules is crucial for the fabrication of functional polymer-based materials for biomedicine and will greatly enhance the competitiveness of Europe in the field. Such conceptual understanding can only be achieved based on a rational interdisciplinary approach, in which theory and simulations guide experiments. Our work plan includes the design, synthesis and characterization of novel macromolecular architectures dictated by theoretical and simulation outcomes on the properties of the materials, followed by toxicity and in vitro/in vivo testing of the materials/structures and industrial feasibility studies. The macromolecular assemblies will be investigated as complex carriers enabling (1) prolonged retention in the eye and (2) controlled ocular drug release under external stimuli (i.e. temperature, light, pH). The synergy resulting from the cooperation between world-leading in their respective fields academic groups and companies though the effective secondments plan will provide a unique interdisciplinary research and training environment that will allow to address unmet challenges in the area and will ensure European leadership in cutting-edge technologies.

The INTERfaces program will train 14 ESRs within an EID network jointly designed by European academic and industry partners in innovative research projects dedicated to developing clean bioprocesses for the production of chemicals. The assembly of biocatalysts to reaction sequences allows avoiding steps for isolation and purification of intermediates and thus a significant improvement of the environmental footprint of catalytic processes. The main goal of INTERfaces is the extension of this concept towards multi-step biocatalytic reactions in immobilized form. These “Heterogeneous Biocatalytic Reaction Cascades” will greatly facilitate re-use of the catalysts and further simplify downstream-processing. INTERfaces combines material science and protein engineering to design tailored enzymes and (bio-based) materials that will complement each other to obtain optimized heterogeneous biocatalysts. These tools will be applied to solve synthetic challenges in the use of two biobased monomers as starting materials to synthesize products for application fields like antioxidants and biopolymers. Process optimization and up-scale in industry will reveal key factors for synthetic utilization of the biocatalysts. INTERfaces emphasizes particularly the engineering of the designed cascades in solid phase. This includes the design of reactors, use of computational modeling tools, application of the right operational modes, and reaction medium needed for desired space-time-yields and product titers. Commercial relevant processes will be up-scaled together with industry for technical implementation. 13 Non-academic partners ranging from high-tech SMEs to large producing companies and 9 academic institutions offer an intersectoral and interdisciplinary environment to provide 14 Ph.D. candidates with outstanding employability profiles for the European Biotech Sector. Dedicated workshops and well-balanced supervisory team aim at increasing the gender diversity in biotech research.
