Microcapsule generating system and method of using same |
| abstract |
Spherical microcapsules (38) containing tissue or living cells are formed with a diameter of less than 300 νm using an air knife (2) constructed according to the present invention. The air knife includes a needle (14) and an air sleeve (26) positioned eccentrically around the needle. An alginate solution containing the biological material to be encapsulated is forced through the needle, while pressurized air is introduced into the air sleeve. The pressurized air breaks up the alginate being discharged from the needle. The resultant alginate droplets (34) fall into a collecting tank (4) where they contact a gelling medium (36), such as CaC12, so that the outer surface of these droplets harden and microcapsules are formed. In addition to being eccentrically positioned to facilitate very small droplet formation, the needle preferably has a beveled, pointed discharge end (50) to enhance droplet size reduction. |
