The old UK sci-fi television series, Blakes 7, which aired in 1970's had this as one of their predicted technologies.
Entire portions of machinery would regenerate after being exploded in sabotage.
Grids of "radiation mine wire" would after being cut, would have the ends of the cable seek each other out and it would grow to join up again. The strategy to bypass this grid/minefield of interlaced wire, would be to fire the blaster across it clearing a path and then to run through it within 8 seconds before it regenerates.
While it was a bit fantastical for the time, I'm sure some hand-waving could justify nanotech as the way this TV tech might be realised.
