Got a cut? Spray it away

Avita Medical, a California biotech firm, has developed a spray-on skin to treat burns.

Making the spray takes only 30 minutes, the company says. Technicians take a skin sample from the patient and turn it into a liquid suspension that can be sprayed over an area 80 times the size of the sample.

Trial outcomes show that burns treated with the spray-on suspension healed faster and looked better than treatments using conventional skin grafts, the company says. The better outcomes are due in part to the speed with which the spray can be made and applied.

The spray can not only improve recovery from burns, but also could be used to repair other kinds of skin abnormalities – including being sprayed over areas from which tattoos have been removed, likely a booming business in the next decade.
