Silicate cross-linked bio-nanocomposite hydrogels from PEO and chitosan.
The compositions and the multi phase structures of bio-nanocomposite hydrogels made from silicate cross-linked PEO and chitosan are related to some of their physical and biological properties. The gels are injectable and self-healing because the cross-linking is physical and reversible under deformation. The presence of chitosan aggregates affects the viscoelastic properties and reinforces the ...
متن کاملRheological study of genipin cross-linked chitosan hydrogels.
This paper reports the rheological behavior of chitosan solutions that have been cross-linked with different amounts of genipin, at body temperature and physiological pH. The effect of the cross-linker loading on the rheological properties of hydrogels has been evaluated. The oscillatory time sweep method was used to monitor the dynamic viscoelastic parameters during in situ (i.e., in the rheom...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Enzymatically cross-linked hydrogels and their adhesive strength to biosurfaces.
OBJECTIVES To design an in-situ gelling hydrogel capable of solidifying rapidly under physiologic conditions into a hydrogel capable of adhering tissue surfaces together. DESIGN Multifunctional polymers containing covalently bound peptide substrates of transglutaminase were designed. EXPERIMENTAL VARIABLE Enzyme cross-linked hydrogels were compared with commercial fibrin tissue adhesive. ...
متن کاملImproving the mechanical and thermal properties of gelatin hydrogels cross-linked by cellulose nanowhiskers.
This study demonstrates the preparation of a renewable and biocompatible hydrogel with superior mechanical properties consisting of a gelatin matrix cross-linked with oxidized cellulose nanowhiskers. We found an increased degree of chemical cross-linking (0.14-17%) between gelatin and nanowhiskers with the increased amount of aldehyde contents (0.062-0.230mmolg(-1)). (1)H nuclear magnetic reson...
