A preliminary study on sodium hyaluronate loaded polyvinyl alcohol nanofiber webs obtained via roller electrospinning

NIR light-triggered photodynamic antibacterial nanofiber membrane based on polycaprolactone and phthalocyanine derivative for biomedical applications

“…Otherwise, the previous study employed polyvinyl alcohol and hyaluronic acid as scaffolds, which yielded average roughness values ranging from 3.5 to 5.5 μm across different concentrations of hyaluronic acid. 38…”

“…Otherwise, the previous study employed polyvinyl alcohol and hyaluronic acid as scaffolds, which yielded average roughness values ranging from 3.5 to 5.5 mm across different concentrations of hyaluronic acid. 38 The physiological stability of nanobers composites is essential during their application, as the rate of degradation should align with the improvement in functional recovery. The deterioration of the control and nanocomposite nanobers mats was examined in a PBS solution over a period of 15 days.…”

Looking beyond biology: glycosaminoglycans as attractive platforms for energy devices and flexible electronics

“…H 2 O/EG blends are known to present a different The results of the conductivity measurements performed on solutions where HA coexists with another polymer are collected in Table 6. Once again, the vast majority of the tested combinations of HA with a polymer (poly(ethylene oxide) (PEO), 178,193,197 poly(vinyl alcohol) (PVA), 193,[198][199][200][201] gelatin, 175,202,203 CHT, 204,205 or poly(aspartic acid) 187 ) afforded conductivities comparable to those observed for pure HA aqueous solutions.…”

“…Two synthetic polymers, PEO 178,193,197 and PVA, 193,[198][199][200][201] were also combined with HA (Table 6). In practically all of the tested mixtures, the conductivity did not improve with respect to that of pure HA solutions (Tables 4 and 5).…”

Analysis of Chemisorbed Tribo-Film for Ceramic-on-Ceramic Hip Joint Prostheses by Raman Spectroscopy

“…Furthermore, the molecular weight of HA is significantly related to its rheological properties [ 21 ]. Due to presence of several carboxyl and hydroxyl groups, HA can be chemically modified [ 17 , 22 ]. Under specific conditions, an acid-protein complex forms a protective gel of concentrated fluid compressed between the cartilage surfaces [ 21 , 23 ].…”
