Prof. Timothy Deming (UCLA / Fulbright-Tocqueville Distinguished Chair à Chimie Bordeaux) donnera jeudi 23 juin à 16 h un séminaire intitulé Synthesis and applications of polypeptide materials.
Our lab has recently developed synthetic methods that allow incorporation of unprecedented levels of functionality into polypeptide materials. We report on the design, synthesis and properties of stimuli responsive polypeptide motifs that are able to respond differently to different individual stimuli, such as redox, temperature, or enzymes. These materials allow multimodal switching of polypeptide properties to obtain desirable features, such as coupled responses to multiple external inputs. The reversible, multi-responsive nature of these polypeptides makes them particularly attractive as components in molecular devices or nanoscale assemblies capable of sequential, or triggered, responses to different stimuli. The use of these motifs in the development of self-assembled materials such as hydrogels and vesicles for biological applications will be described.
