Summary
Alginate and aloe vera gel membranes were developed for wound healing. The 3D membranes exhibited enhanced swelling and excellent biocompatibility, showing promise for advanced wound dressings.
Area of Science:
- Biomaterials Science
- Tissue Engineering
- Regenerative Medicine
Background:
- Effective wound dressings are vital for tissue regeneration, requiring moisture balance and infection prevention.
- Alginate (AL) and aloe vera gels (AVGs) are recognized for their therapeutic properties in skin treatments.
- Combining AL with AVG offers a promising strategy for developing advanced wound healing materials.
Purpose of the Study:
- To prepare and characterize 2D and 3D alginate-aloe vera gel (AL-AVG) membranes for wound healing applications.
- To investigate the influence of AVG content, ionotropic gelation, and membrane structure (2D vs. 3D) on material properties.
- To evaluate the swelling, degradation, and cytotoxicity of the developed AL-AVG membranes.
Main Methods:
- Two-dimensional (2D) AL-AVG membranes were fabricated via casting.
- Transparent, nanoparticle-enhanced 3D AL-AVG membranes were produced using ultrasonication and ionotropic crosslinking.
- Material properties were assessed using Scanning Electron Microscopy (SEM), swelling ratio tests, degradation studies under varying pH and enzymatic conditions, and cytotoxicity assays with ATCC CCL 163 and ATCC CCL 81 cells.
Main Results:
- 3D AL-AVG membranes exhibited increased surface roughness compared to 2D counterparts.
- Higher AVG content led to increased swelling ratios in the 3D membranes.
- Membrane degradation was more significantly influenced by pH variations than by lysozyme presence.
- All AL-AVG membranes demonstrated excellent biocompatibility, with over 90% cell viability after 48 hours.
Conclusions:
- 3D AL-AVG membranes possess superior swelling properties and excellent biocompatibility, making them suitable for wound dressing applications.
- The developed membranes offer tunable properties based on AVG content and structural design.
- These findings support the potential of AL-AVG composite membranes as advanced wound healing materials.
