There's no way to be certain. This is just my guess.

I think you will be able to. The devs have said that anything you get is yours to keep; if you keep your Black Nanos stockpiled, and don't tear down your Infection Test Facility, you *should* be able to use it in the future.

No promises, though. Z2Live can be very unpredictable.
