AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The covalent attachment of poly(ethylene glycol) (PEG) to therapeutically active proteins (PEGylation) has become an important method to deal with the pharmacological difficulties of these polypeptides, such as short body-residence times and immunogenicity ...
A series of poly(ethylene glycol-co-isopropylidene glyceryl glycidyl ether) (P(EO-co-IGG)) random copolymers with different fractions of 1,2-isopropylidene glyceryl glycidyl ether (IGG) units was synthesized. After acidic hydrolysis a new type of "function ...
Polypeptides derived from naturally occurring a-amino acids have emerged as a unique and versatile family of bio-inspired biomaterials that can be tailor-made for varying biomedical applications such as controlled drug release, gene delivery, tissue engine ...
In natural systems, highly synergistic non-covalent interactions among biomolecular components exert mesoscopic control over hierarchical assemblies. We herein present a multicomponent self-assembly strategy to tune hierarchical supramolecular polymer arch ...
The lower critical solution temperature (LCST) behavior of novel poly(ethylene glycol) (PEG)-based copolymers bearing multiple functional groups, obtained by anionic ring-opening (co)polymerization (AROP), has been investigated. Variable comonomer ratios o ...
Novel calcium alginate poly(ethylene glycol) hybrid microspheres (Ca-alg-PEG) were developed and evaluated as potentially suitable materials for cell microencapsulation. Grafting 5-13% of the backbone units of sodium alginate (Na-alg) with alpha-amine-omeg ...
In this study, the residue-selective modification of proteins with polymers at arginine residues is reported. The difficulty in modifying arginine residues lies in the fact that they are less reactive than lysine residues. Consequently, typical chemo-selec ...
Bioactive hydrogels formed from the Michael-type addition reactions of end-functionalized poly (ethylene glycol) macromers with thiol-containing protease-sensitive peptide crosslinkers have previously been described as matrices for cell-induced enzymatic r ...
Bioactive hydrogels formed by Michael-type addition reactions of end-functionalized poly(ethylene glycol) macromers with cysteine-containing peptides have been described as extracellular matrix mimetics and tissue engineering scaffolds. Although these mate ...
A one-step extrusion process under physiological conditions yielded calcium alginate-poly-(ethylene glycol) hybrid microspheres (Alg-PEG-M), for which the physical properties were adjustable by the macromolecular characteristics of the components, their co ...
