In this study, the effect of gamma irradiation (10 kGy) on proteins extracted from animal hide, scales, and wool was evidenced by calorimetric (μDSC) spectroscopic (IR, circular dichroism, EPR) methods. Keratin obtained sheep wool, collagen bovine gelatin fish scales. The μDSC experiments that influences thermal stability these differently. keratin decreases, while a resistance to denaturation noticed for gelatins after irradiation. analysis IR spectra demonstrated determines changes in...
This study analyzes the physico-chemical properties of interpenetrated polymer networks (IPNs) and semi-IPN resulting from cross-linking chitosan with glutaraldehyde alginate Ca2+ cations, as a function order in which agents are added to mixture. Three methods were used assess differences between systems: rheology, IR spectroscopy, electron paramagnetic resonance (EPR) spectroscopy. While rheology spectroscopy commonly characterize gel materials, EPR is rarely used, but has advantage...
Fast, reliable methods for characterizing the micelle-to-gel transition in emerging Pluronic F127/polysaccharide materials are essential tailoring their applications as situ gelling delivery systems. This study describes a simple fluorimetric method based on response to gelation of molecular probe thioflavin T (ThT). The techniques employed (second derivative) steady-state and synchronous fluorescence. capabilities ThT reporter tested three model systems: F127 (P16.6%), F127/alginate...
