| Summary: | Burn is a major skin injury that mostly occurred worldwide including in
Indonesia. For second degree burns, special treatment should be given in order to
creating a suitable wound healing environment. Besides hydrogel wound
dressing as primary care, electrical stimulation can be applied as additional
treatment for promoting wound healing. Here, we used the tissue engineering
concept to create novel conductive hydrogel made of polyvinyl alcohol (PVA),
graphene-based material (GBM), and aloe vera extract (Av) through freeze-thaw
process. We synthesize the PVA/GBM/Av hydrogel and examine its potential as
wound dressing. We found that it exhibited excellent hydrophilicity with contact
angle between 15-31 degrees, electrical conductivity within the range of 0.0102-
0.0154 S/m which is comparable to human skin tissue, and good stability with
WR of 80% after 14 days. We also presented that the addition of GBM would
inhibit the growth of gram-positive Staphylococcus aureus with the lowest
bacterial population was observed in PVA/GO which is 1.74 x 107 cFu/mL after
1-day incubation. In summary, our fabricated hydrogels showed their potential
as wound dressing with good electrical conductivity. |
