Electrospun chitosan-based nanocomposite mats reinforced with chitin nanocrystals for wound dressing

Synthesis, characterization, and antimicrobial properties of novel double layer nanocomposite electrospun fibers for wound dressing applications

“…Hence, to obtain nanofibers, chitosan can be mixed with readily spun polymers such as PVA 7,22,23 and polyethylene oxide (PEO). 24 PVA is considered as one of the oldest and most frequently used synthetic polymers with good biocompatibility properties. 25 In order to enhance the antibacterial activity of dressing mats against both drug-sensitive and drug-resistant pathogenic bacteria, Lee et al incorporated silver nanoparticles (AgNPs) into a blend of chitosan and PVA polymeric mats.…”

3-Dimensional porous nanocomposite scaffolds based on cellulose nanofibers for cartilage tissue engineering: tailoring of porosity and mechanical performance

“…8,9,14,15 Our earlier studies have also demonstrated that solution cast brous nanocomposite structures with high cellulose nanobers concentrations (75 wt%) and collagen provide mechanical performance suitable for ligaments. 8,9 Also, our previous studies have demonstrated the noncytotoxicity of nanocellulose from different sources and their potential in medical applications.…”

Effect of crosslinking procedure on structural, thermal, and functional performances of cellulosic nanofibers: A comparison between chemical and photochemical crosslinking

“…Mechanical strength and increase in modulus as well as ultimate strain reduction after crosslinking is an expected behavior. 4 In fact forming intra-and inter-fiber bonding leads scaffold to be more resistant to deformation. Lower tensile strain after GA crosslinking is also attributable to reduced molecular mobility in the crosslinked polymer network.…”

“…3 In some cases, crosslinking pose unwanted structural or functional effects on final scaffold. 4,5 Chemical crosslinking, which is based on using small molecules containing reactive groups capable of forming covalent bonds with polymer functional sites, suffers from the potential cytotoxicity of the residual crosslinkers and its side-effects on biocompatibility should be always considered. 2 When using photocrosslinking, there is always the possibility of either polymer chain scission or crosslinking.…”
