Abstract
The present invention relates to an apparatus for single cell trap and position fixing of the trapped cell thereof, and specifically, it induces cell movement from where fluid flows strongly to where the fluid flows weakly, by injecting pressed air to an air channel to modify a thin film of a vibrator, and therefore to induce the fluid flow. Further, the present invention relates to an apparatus which can fix the cell position as well as minimizing the external stimulation to the cells, wherein single cells are trapped in a region wherein the fluid flows are minimized and their positions are fixed using the effect that the fluid flows induced by the vibrators are offset one another because the vibrators are formed symmetrically one another.
Claims7
An apparatus for single cell separation and position fixing, which comprises:
- a) a first layer containing a fluidic channel wherein fluid containing cells flows;
- b) a second layer containing plural air channels wherein air is injected from the outside;
- c) a glass substrate wherein the first and the second layers are laminated;
- and
- d) thin film vibrators which are located between the air and fluidic channels and formed at one end of each of the air channels,
- wherein the plural thin film vibrators form a square and the plural thin film vibrators are located at each corner of a square area.
Dependencies are inferred from the claim text.
