Chitosan-based glycerol-plasticized membranes: bactericidal and fibroblast cellular growth properties

Improving the Durability of Chitosan Films through Incorporation of Magnesium, Tungsten, and Graphene Oxides for Biomedical Applications

“…A reduced contact angle was produced as a result of the higher surface energy, which made it simpler for water molecules to disperse over the membrane surface [53] . This hydrophilic characteristic is advantageous for situations where the membrane has to interact with aqueous solutions or be physically linked to the surroundings [52,53] . The modified chitosan membrane's improved hydrophilicity is probably the result of a number of causes.…”

“…However, the incorporation of WO 3 and MgO NPs into the CS membrane diminished the contact angle to almost 40.19±1.24°, which induces hydrophilicity and encourages their ability to be physically cross‐linked with the surrounding Figure 5( f ), [49,50] thus controlling the ratio of embedded nanoparticles through the scaffolds play a crucial role in adjusting its hydrophilic properties [51] . The contact angle is a measure of the wettability of a surface, where a smaller contact angle indicates increased hydrophilicity or water‐attracting properties [52,53] . The surface characteristics of the chitosan membrane were changed by adding WO 3 and MgO nanoparticles.…”

“…Second, the nanoparticle‐induced surface roughness might increase the surface area on which water can adhere, decreasing the contact angle [53] . The nanoparticles chemical makeup itself may also have inherent hydrophilic qualities that add to the modified membrane overall hydrophilicity [52] …”

“…[51] The contact angle is a measure of the wettability of a surface, where a smaller contact angle indicates increased hydrophilicity or water-attracting properties. [52,53] The surface characteristics of the chitosan membrane were changed by adding WO 3 and MgO nanoparticles. The surface roughness or changes brought on by the nanoparticles probably increased the surface area open to interaction with water molecules.…”

“…[53] This hydrophilic characteristic is advantageous for situations where the membrane has to interact with aqueous solutions or be physically linked to the surroundings. [52,53] The modified chitosan membrane's improved hydrophilicity is probably the result of a number of causes. WO 3 and MgO nanoparticles might firstly produce active areas on the surface that draw and bind water molecules.…”
