Four years ago, scientists from the University of Toronto (Canada) has created a 3D printer that prints skin for the treatment of burns.
Now it was improved, making portable gadget will be able to print skin directly on deep wounds, closing them and accelerating the healing, writes with reference to
Printer works like stationery tape corrector, but instead of gluing paper tape in place to “fix” it produces narrow strips of fabric on the basis of alginic acid is a viscous rubber-like substance extracted from red, brown and green algae.
The lower part of each strip consists of biochannel that contains skin cells and collagen — a protein that, together with fibrin plays a critical role in wound healing.
The device weighs less than 1 kg and requires minimal training before use. It may cover the wound with skin for two minutes. The unit was tested on rats and pigs.
Now scientists plan to expand the size of the covered wound surfaces and hope to begin clinical trials in humans.”Our portable printer will be able to adapt tissue to specific patients and types of wounds,” says Navid Hakimi, who led the study.
