Maria Demeter,Viorica Meltzer,Ion Călina,Anca Scărișoreanu,Marin Micutz,Mădălina Georgiana Albu Kaya +5 more
TL;DR: In this paper, highly elastic and superabsorbent hydrogels of collagen-polyvinyl pyrrolidone (PVP)-poly(acrylic acid) (PAA)-poly-ethylene oxide (PEO) quaternary copolymer were obtained using e-beam crosslinking reaction to be used for soft tissue engineering.

One Step e-Beam Radiation Cross-Linking of Quaternary Hydrogels Dressings Based on Chitosan-Poly(Vinyl-Pyrrolidone)-Poly(Ethylene Glycol)-Poly(Acrylic Acid)
TL;DR: The hydrogels proved to have a significant loading capacity of ibuprofen, being able to incorporate a therapeutic dose for the treatment of severe pains, and to have the best swelling properties in different pH solutions.

State of the Art of Hydrogel Wound Dressings Developed by Ionizing Radiation
TL;DR: The development of an ideal hydrogel wound dressing with excellent characteristics is currently a significant demand in wound therapy as discussed by the authors , and the ideal wound dressing must provide a moist environment between the wound and the dressing, promote wound healing, absorb excess exudate and toxins, be completely sterile, and not adhere to the wound.
Correlations on the Structure and Properties of Collagen Hydrogels Produced by E-Beam Crosslinking
TL;DR: In this paper, a collagen hydrogel using collagen exclusively produced in Romania, was obtained by electron beam (e-beam) crosslinking, and the authors concluded that irradiation with e-beam up to 25 kGy induces crosslink processes in collagen structure without producing advanced degradation processes.
Radiation induced degradation of xanthan gum in the solid state
Murat Şen,Hande Hayrabolulu,Pınar Taşkın,Murat Torun,Maria Demeter,Mihalis Cutrubinis,Olgun Güven +6 more
TL;DR: In this article, the effect of ionizing radiation on xanthan gum was investigated and it was observed that the dose rate was an important factor controlling the chain scission yield (G(S)), and degradation rate constants (k).
