Metal-Promoted Self-Assembly Of Collagen Mimetic Peptides Into Biofunctional Scaffolds For Stem Cell Delivery With The Aim Of Tissue Regeneration, Kevin Strauss
Open Access Theses
Collagen is a strong, sturdy, but malleable, protein found abundantly in the extracellular matrix. Consequently, it has become an invaluable biomaterial for use in regenerative medicine. However, natural collagen poses difficulties when it comes to customization and structural control, as well as the risk of infectious prions from animal sources. Our approach utilizes shorter, synthetic collagen mimetic peptide sequences. These peptides retain the incredible triple helical stability of natural collagen but can be modified with versatile metal-binding ligands. In the presence of an appropriate metal ion, the peptides self-assemble into diverse, three-dimensional morphologies. The peptide NCoH, functionalized with N-terminal NTA …

Size And Chemistry Selective Membranes From Block Polymer Templates, Ryan A. Mulvenna
Open Access Dissertations
The use of block polymers continues to gain attention with their myriad applications in industry for advanced applications in biology, medicine, electronics, and separations. The ability of block polymers to self assemble into ordered states on the nanometer level makes these materials suitable for applications that mandate structural order on this scale. By tuning the chemistry of these block domains, we may explore their utilization for advanced separations.
In this dossier, we detail the efforts into the controlled radical polymerization of polyisoprene-b-polystyrene-b-poly( N,N-dimethylacrylamide) (PI-PS-PDMA) via. a facile reversible addition-fragmentation chain transfer (RAFT) mechanism. For this …
