Diabetics are 15 times more likely to have an amputation due to sores and ulcers on their feet, so even minor cuts, scrapes, and scrapes should be carefully monitored.
For this reason, the researchers used electricity to promote healing, which is not a new concept, but found that skin cells are electrotactic and will move in the direction of the electric field. Researchers have used this principle to send electric shocks to cells to heal wounds faster, especially in diabetics.
The researchers created a microfluidic platform that combines laser-induced graphene with an integrated hydrogel capable of driving DC electrical stimulation for hours.
They found that DC stimulation resulted in faster wound closure in all cases and did not adversely affect cells. The wound healing effect was stronger when the current was applied to only one side of the wound. After 12 hours of unidirectional stimulation, cells closed by approximately 34% compared to 12% in unstimulated control cells.
