Fast, reliable methods for characterizing the micelle-to-gel transition in emerging Pluronic F127/polysaccharide materials are essential for tailoring their applications as in situ gelling delivery systems. This study describes a simple fluorimetric method based on the response to gelation of the molecular probe thioflavin T (ThT). The techniques employed are (second derivative) steady-state and synchronous fluorescence.

Keratin was obtained from sheep wool, collagen and bovine gelatin from bovine hide, and fish gelatin from fish scales. The μDSC experiments evidenced that gamma irradiation influences the thermal stability of these proteins differently.

- This study investigates how the order of adding cross-linking agents affects the properties of interpenetrated polymer networks (IPNs) made from chitosan and alginate.
- It utilizes three methods—rheology, IR spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy—to analyze the physical and chemical characteristics of the polymer systems.
- Findings indicate that the order of introducing cross-linkers impacts both the gel behavior and the dynamic structure of the network, with the alginate network significantly influencing the overall characteristics of the IPN systems.
