Application of Polysaccharides in Hydrogel Biomaterials

Area of Science:

• Biomaterials Science
• Wound Healing Research
• Polymer Chemistry

Background:

• Hydrogel biomaterials incorporating natural compounds are crucial for wound healing.
• Sodium alginate and polyethylene glycol diacrylate (PEGDA) are common hydrogel components.
• Ethylene ginger extract (EEI) offers potential therapeutic properties for wound management.

Purpose of the Study:

• To synthesize and characterize novel hydrogel biomaterials for wound healing applications.
• To evaluate the effects of sodium alginate, PEGDA, and EEI on hydrogel properties.
• To assess the potential of developed hydrogels as advanced wound dressings.

Main Methods:

• Thermogravimetric analysis (TG)
• Differential scanning calorimetry (DSC)
• Dynamic mechanical analysis (DMA)
• Water absorption testing
• Microscopic analysis

Main Results:

• The 4%Alg/12%PEGDA hydrogel exhibited optimal water absorption and thermal stability.
• The addition of EEI negatively impacted water absorption but enhanced hydrophilic properties and ionic conductivity in the 4%Alg/12%PEGDA/12%EEI hydrogel.
• Both PEGDA and EEI increased hydrogel acidity, promoting an acidic wound microenvironment.

Conclusions:

• The 4%Alg/12%PEGDA/12%EEI hydrogel shows promise as a high-performance wound dressing due to its hydrophilic nature, ionic conductivity, and ability to maintain an acidic pH.
• Further research is warranted to fully explore the therapeutic potential of this novel hydrogel formulation for wound management.
