Any idea how they do it now with skin grafts?
Well, my thinking was that this is an entirely different mechanic.
With the skin graft, they simply keep the grafts in a sterile environment
They're shooting these tiny particles through air, onto the skin, and it seems impossible to me be certain that the particles are traveling through "first air."
Granted, this isn't an IV, but these burn victims are definitely immunosuppressed and vulnerable..
