Apparatus and method for machining microchamber for cell culture
This invention relates to a method and apparatus for process cell cultures. The apparatus comprises a micro-chamber comprising no more than one absorption layer and at least one gel layer, in this order, laminated on a transparent base plate having no conspicuous absorbency in visible and infrared regions, and at least one light source. The absorption layer has absorbency in visible and infrared regions, and the gel-like material is a substance which has a gel dissolution temperature of 100 degree C. or less, solates when heated and is in a gel state at room temperature and has absorbency for a specific wave length of visible and infrared regions. The light source is monochromatic light in the specific wave length. The light source is disposed such that it irradiates on the absorption layer and/or gel layer, with the exception that when no absorption layer is provided, at least two layers each composed of a gel-like material are laminated on the transparent base plate.
1. A micro-chamber processing apparatus for cell culture comprising a micro-chamber and at least one light source, wherein said micro-chamber comprises at least two gel layers each composed of a gel material laminated on a transparent base plate having no conspicuous absorbency in visible and infrared regions, said gel material is in a gel state at room temperature, which has a gel dissolution temperature of 100 degree C. or less and solates when heated, said gel material has absorbency at a specific wave length of visible or infrared region, said light source has a monochromatic light at said specific wave length, and said light source is disposed such that it irradiates on said gel layers, wherein the at least two gel layers each have a different absorption wave length or a different dissolution temperature.
2. The apparatus as in claim 1 further comprising a measuring means for confirming the position of a light irradiated from a light source during irradiation.
3. The apparatus as in claim 1 wherein the light source is disposed such that it can focus and irradiate a light on either an absorption layer or a gel layer.
4. The apparatus as in claim 1 wherein the light source comprises two or more light sources having each a different wave length, at least one wave length of which is an absorption wave length of either gel layer.
5. The apparatus as in claim 1 wherein the light source comprises one light source, a wave length of which is an absorption wave length of either gel layer.
6. The apparatus as in claim 1 wherein no absorption layer is provided.
7. The apparatus as in claim 2 wherein the light source is disposed such that it can focus and irradiate a light on either of an absorption layer or a gel layer.
8. The apparatus as in claim 2 wherein the light source comprises two or more light sources having each a different wave length, at least one wave length of which is an absorption wave length of either gel layer.
9. The apparatus as in claim 2 wherein the light source comprises one light source, a wave length of which is an absorption wave length of either gel layer.
10. The apparatus as in claim 2 wherein no absorption layer is provided.
11. The apparatus as in claim 7 wherein the light source comprises two or more light sources having each a different wave length, at least one wave length of which is an absorption wave length of either gel layer.
12. The apparatus as in claim 11 wherein the light source comprises one light source, a wave length of which is an absorption wave length of either gel layer.
13. The apparatus as in claim 12 wherein no absorption layer is provided.
