text: If antibubbles can be stabilized they can be used to form a long lasting froth — antifoam. Possible uses for antifoam are as a lubricant or using the thin passageways permeating antifoam as a filter for air or other gasses.
  Antibubbles themselves could be used for chemical processes such as removing pollutants from a smokestack. Replacing the air in antibubble shells with another liquid could be used for a drug delivery system by creating a shell of liquid-polymer around a drug. Hardening the polymer with ultraviolet light would create a drug filled capsule.
  Microscopic antibubbles have demonstrated their feasibility in harmonic imaging. 
  It has been proposed to incorporate therapeutics into antibubble cores. Such drug-loaded antibubbles might be used in ultrasound-guided drug delivery, where acoustic waves create sufficient pulsations of the antibubble surface to release its drug-containing core.
