Rheological characterization of hydrogels formed by recombinantly produced spider silk
Many fibrous proteins such as spider silks exhibit impressive mechanical properties and are highly biocompatible leading to many potential biomaterial applications. For applications such as tissue engineering, polymer hydrogels have been proposed as an effective means of producing porous but stable scaffolds. Here, nanofiber-based hydrogels were produced from engineered and recombinantly produc...
متن کاملFlow and Thixotropic Parameters for Rheological Characterization of Hydrogels.
The goal of this paper was to design several sodium carboxymethylcellulose hydrogels containing a BCS class II model drug and to evaluate their flow and thixotropic properties. The rheological measurements were performed at two temperatures (23 °C and 37 °C), using a rotational viscometer. The hydrogels were stirred at different time intervals (10 s, 2, 5, 10 and 20 min at 23 °C, and 10 s, 2 an...
متن کاملPolyacrylamide-Clay Nanocomposite Hydrogels: Rheological and Light Scattering Characterization
The free-radical polymerization of acrylamide in aqueous clay dispersions and the structure of the resulting polymer-clay nanocomposite hydrogels have been investigated by rheometry using oscillatory deformation tests. Laponite was used as clay particles in the hydrogel preparation. The reactions were carried out with and without the presence of the chemical cross-linker N,N′-methylenebis(acryl...
متن کاملSynthesis and Characterization of Poly(ethylene glycol) Dimethacrylate Hydrogels
Facile synthesis and detailed characleri7.ation of photopolymerizable and biocompatible poly(ethylene glycol) dimetbacrylates (PEGDM) and their hydrogels are described. Combined analyses of H NMR and MALDI-TOF MS confirmed the formation of prepolymers of high purity and narrow mass distribution (PD < 1.02). A systematic investigation into the struCtW'e and mechanical properties of PEGDM hydroge...
متن کاملGlucose-sensitivity of glucose oxidase-containing cationic copolymer hydrogels having poly(ethylene glycol) grafts.
Glucose oxidase and catalase were immobilized on poly(diethylaminoethyl methacrylate-g-ethylene glycol) gels by copolymerization of the constituent monomers and the functionalized enzyme solutions. The hydrogels were prepared in the form of discs and microparticles. The amount and the activity of enzymes immobilized in the matrix were determined. The hydrogels were tested for their response to ...
