This volume describes the preparation of shape-defined and/or bioactive peptide-polymer hybrid materials, using sequence-defined, initiator-modified peptides, and grafting synthetic polymers directly from the peptide by atom transfer radical polymerization (ATRP). In one example, a bioactive peptide sequence, which is known to promote the matrix-adhesion of living cells, is conjugated to a synthetic polymer, which is known to prevent cell-adhesion in thin film configuration. This interesting combination of two very contrary properties in a single molecule was further utilized to design surfaces that spatially control the attachment and growth of living cells (i.e. design of novel cell-chips) on solid substrates. In a second part of the thesis, a cyclic D-alt-L-peptide was modified in situ with synthetic polymeric arms. So-prepared coil-ring-coil peptide polymers show an interesting self-assembly into core-shell like nano-rods, where the core consists of stacked peptide rings that are hold together by multiple weak interactions (H-bonds), and the shell consists of terminally attached macromolecules. In conclusion, this thesis shows that it is possible to in situ prepare a novel class of molecules, i.e. peptide-polymer conjugates, where the peptide can either implement a distinct bioactive property into synthetic polymers, or where a the peptide can act as a structure-guiding module to organize the overall structure of bottom-up designed supramolecular polymers.
