Radiation crosslinking polymerization of sterculia polysaccharide–PVA–PVP for making hydrogel wound dressings

Research on a novel poly (vinyl alcohol)/lysine/vanillin wound dressing: Biocompatibility, bioactivity and antimicrobial activity

“…Once, materials such as medical absorbent cotton [1] and pledget [2] were widely used as wound dressings owing to them isolated the wound from outside environment. With the development of technology, it is found that wound healing is a series of events that is quite complex and incompletely understood [3]. During wound healing, wound barrier formation is a critical process.…”

Influence of Poly (Ethylene Glycol) on the Characteristics of γ Radiation-Crosslinked Poly (Vinyl Pyrrolidone)-Low Molecular Weight Chitosan Network Hydrogels

“…The broad band with less absorbance of CH bending around 2950 -2900 cm -1 was observed in Figure 1(c) compared to Figure 1(b) because of the formation of crosslink network of PVP (Singh & Pal 2011). The covalent bond of PVP crosslinked attributed by the weak vibration of -CH 2 -at 1420 cm -1 of hydrogel L. The aliphatic C-H stretch at 2880 cm -1 band indicated intense peak in PEG yet weakened in (e).…”

“…The broad absorption band around 1010 -1080 cm -1 of Figure1(a) attributes to the glycosidic linkages of LMC (Abad et al 2003). The strong band at 1653, 1421, 1287 and weak band at 2917 cm -1 of PVP Figure 1(b) were assigned to C=O stretching, C-N stretching, O-H bending and C-H stretching vibrations, respectively (Can 2005;Singh & Pal 2011;Yang et al 2010).…”

Preparation, characterization and evaluation of chitosan macroporous for potential application in skin tissue engineering

“…However, the large scale skin defects could not heal spontaneously, which still is the major problem in the surgical field [1]. Since the early 1980s, numerous skin substitutes including autografts, allografts, and xenografts have been developed to promote wound healing [2].…”
