Air-filled polyvinyl alcohol capsules can be produced at Surflay in sizes ranging from 3-4 µm. Thanks to a special cross-linking procedure, these bubbles are stable for months, hydrophilic and uncharged. Due to their low density, they slowly float in water to the top.
Some applications / possibilities:
- These microbubles are excellent tools for cell-sorting
- In combination with Layer-by-Layer coatings, further surface functions can be added
- Air in the bubbles can also be exchanged with water in order to create e.g. microreactors
