A new class of water-soluble, amphiphilic star block copolymers with a large number of arms was prepared by sequential atom transfer radical polymerization (ATRP) of n-butyl methacrylate (BMA) and poly-(ethylene glycol) methyl ether methacrylate (PEGMA). A ...
The self-assembly in aqueous solution of hybrid block copolymers consisting of amphiphilic ?-strand peptide sequences flanked by one or two PEG chains was investigated by means of circular dichroism spectroscopy, small-angle X-ray scattering, and transmiss ...
The morphology in the solid state of a series of triblock copolymers comprising a poly(ethylene glycol) (PEG) midblock and symmetric poly(γ-benzyl-L-glutamate) (PBLG) end blocks has been studied using X-ray scattering and microscopy techniques. Transmissio ...
Peptide based and peptide hybrid materials represent two interesting and challenging classes of biomaterials. Both classes consist of and contain, respectively, one or more polypeptide blocks, endowing the resulting polymers with enhanced self-assembly pro ...
The self-assembly mechanism has been studied in poly(γ-benzyl-L-glutamate)-poly(ethylene glycol)-poly(γ-benzyl-L-glutamate) (PBLG-PEG-PBLG) triblock copolymer melts using X-ray scattering, polarizing optical microscopy, differential scanning calorimetry, a ...
The synthesis of novel hybrid hydrogels by stepwise copolymn. of multi-arm vinyl sulfone-terminated poly(ethylene glycol) macromers and a-w cysteine oligopeptides via Michael-type addns. is described. Crosslinking kinetics, studied by in situ rheometry, ca ...
This paper discusses the solid state and melt nanoscale structure of a series of novel poly(ethylene glycol) (PEG) hybrid di- and triblock copolymers, which contain amphiphilic β-strand peptide sequences. The block copolymers have been prepared via solid-p ...
A one pot synthetic method was developed for prepn. of amphiphilic block copolymers using episulfide anionic polymn. for generating sym. or asym. tri- or multi-block copolymers via living mechanism. The method is based on in situ generated thiolates, which ...
This report demonstrates the feasibility of surface-initiated atom transfer radical polymerization to prepare thin polymer layers ("brushes") that can be functionalized with short peptide ligands and which may be of use as coatings to promote endothelializ ...
Siderophores are natural iron chelators that have been evolutionarily selected to bind to Fe ions with very high binding consts. We utilize these unique properties to bind to metal oxide surfaces using a fragment of the cyanobacterial siderophore anachelin ...
