The large availability of cellulose in nature and the low cost of cellulose derivatives make the cellulosebased hydrogels particularly attractive. New hydrogels were obtained by chemical cross-linking of different cellulose allomorphs (cellulose I, cellulose II and cellulose III) and xanthan with epichlorohydrin. The preparation conditions of the transparent cellulose hydrogels were established...

Ionic hydrogels with excellent flexibility and good conductivity have great potential in diverse electric devices. However, it remains challenging to improve the biocompatibility of ionic hydrogels. Here, natural environment-friendly cellulose nanofiber were prepared without adding any organic active materials. The hydrogel networks free metal ions (Li+/Ca2+/K+) obtained by soaking ion aqueous ...

PVP-CMC and PVP-CMC-BA are designated as medicated hydrogels which are elastic in nature like other gels and solids. This present work was focused on the effect of strain on viscoelastic behavior of these medicated hydrogels. Dynamic frequency sweep test at 10% strain and dynamic strain sweep tests at different angular frequencies were performed on these hydrogels. Freshly prepared hydrogels an...

Abstract Excessive epidural fibrosis attached to the dura mater is major cause of recurrent failed back surgery syndrome after spine surgery. Neutrophil extracellular traps (NETs) promote fibrosis, raising possibility that DNA backbone NETs may be a potential target in therapy fibrosis. Human body temperature-sensitive hydroxypropyl chitin hydrogel solutions were prepared encapsulate DNase I, w...
