  The article does mention this problem and they claim to have been able to pull it off somehow.

  “Mammalian cells are orders of magnitude more sensitive than algae cells, but even with those cells, we were able to detach them with no impact to the viability of the cell,” Vandereydt says.

  What happens when they interact with bubbles?

    Bubbles act as a water/air interface. The lipid membrane of a cell is a wall that has an internal hydrophobic layer made of phospholipids. Phospholipids when introduced to a water/air interface orient their hydrophobic side into the air, away from water. In other words the bubble rips the cell membrane apart by pulling phospholipids out of the membrane.

      The world if even 1% of MIT headlines were true:

        Sure, but trying and failing is the only way we’ve ever accomplished anything.
