I remember Will Smith in I, Robot, spraying his bionic arm with some sort of instant skin to cover up the damage, and that moment round we have something out of the world of science fiction that could be a reality. The spray-on Skin Gun could be the aftermath of a $250 million research project that sprays new, stem-cell infused skin onto a wound to

expedite the healing process to just hours (minutes are still an unrealistic target). Well, it might not be Wolverine’s healing factor but at the very least it is better than waiting for a week for it to heal.
