Abstract: Molecular self-assembly is becoming increasingly important in the development of innovative biomaterials because it offers a great platform for fabricating them with a high level of precision and complexity. A number of building blocks have been explored for developing self-assembling biomaterials, but peptides offer many important advantages. They can be designed to incorporate structural and bioactive domains and form discrete nanostructures that emulate not only the physical architecture but also the chemistry of the extracellular matrix. Through rational design, our group is integrating interacting domains into peptides to drive their self-assembly into well-defined structures and provide signals for cells to adhere, spread or differentiate. This talk will cover our work on the molecular design of biomaterials (membranes, capsules, hydrogels) customized for specific biomedical applications (skin wound healing, cell culture) but also our recent developments on periosteum-like membranes and nanocarriers for targeted intracellular delivery.
