Isolator or Isoshields are a kind of forcefield bubble that is selectively permeable to the atmosphere, temperature and nanosphere where present. Large, static devices can create isolation zones encompassing entire buildings. Smaller, mobile machines have a correspondingly smaller field size. Isodrones are general purpose drones fitted with mobile isoshield generators.
