Unprecedented photolithographic structuring of novel light-sensitive poly(amino acid) materials– a paradigm shift in delivering biocompatible devices
Photolitography, which produces geometrical structures through light-induced polymerisation of monomers with high accuracy, precision and spatial resolution, was a key innovation enabler in the drive for high-performance miniature electronics, which had an unprecedented impact on every aspect of our modern life. Geometrically well-defined microstructures could also be a game changer in the medical device industry, especially in the development of implantable devices with better tissue compatibility, as well as in the discovery of new drugs and treatments.
Current gold standard materials and biomaterial extrusion processing cannot generate the structural resolution to kick-start this new era. The groundbreaking approach of POLINA is to combine a radically new, light-sensitive poly(amino acid) material platform with established and emerging photolithographic patterning techniques to deliver a revolutionary technology that can be exploited for medical devices and next-generation green electronics. Exploring this uncharted territory will be possible through an ambitious multidisciplinary approach delivering breakthroughs in photopolymerisation of amino acids and their lithographic structuring for novel materials with unique biological properties.
The high innovation potential of this technology to overcome current limitations will be demonstrated in three selected examples related to lung diseases, i.e., micropatterned cell surface models, spheroid arrays for lung disease modelling and drug testing as well as tracheal implants. Our intersectoral team of 5 academic groups and 2 SMEs brings together unique scientific expertise in photo and polymer chemistry, biomaterials science, lithographic processing, tissue engineering, clinical expertise and innovation management.
Through POLINA we will pave the way to revolutionise bioprinting, for safer, smarter and affordable medical devices and in the long term a new approach in (bio)electronics.
