Abstract

A method for producing a cell culture article having a synthetic polymer layer for incubating with cells includes diluting one or more (meth)acrylate monomers in a solvent and dispersing the diluted monomers on a surface of the cell culture article. Some or substantially all of the solvent is removed and the monomers are then polymerized on the surface of the article to form the synthetic polymer layer attached to the surface of the article.

Claims (23)

1. A method for producing a cell culture article having a synthetic polymer layer, comprising:

(a) diluting one or more (meth)acrylate monomers in a solvent;

(b) dispersing the diluted monomers on a surface of a cell culture substrate;

(c) removing about 80% or more of the solvent; and

(d) polymerizing the monomers on the surface of the cell culture substrate after removing the about 80% or more of the solvent to form the synthetic polymer layer attached to the surface of the cell culture substrate.

2. The method of claim 1 , wherein removing the solvent comprises evaporating the solvent.

3. The method of claim 1 , wherein the solvent has a boiling point of between about 50° C. and about 100° C.

4. The method of claim 1 , wherein the solvent has a boiling point of between about 70° C. and about 85° C.

5. The method of claim 1 , wherein the solvent is selected from the group consisting of acetone, methanol, ethyl acetate, ethanol, butanone, acetonitrile, 2-propanol, and 2-butanol.

6. The method of claim 1 , wherein the solvent comprises ethanol or 2-propanol.

7. The method of claim 1 , wherein the solvent comprises greater than 95% ethanol.

8. The method of claim 1 , wherein the cell culture substrate is formed from a polymeric material.

9. The method of claim 1 , wherein the cell culture substrate comprises a cyclic olefin copolymer.

10. The method of claim 9 , further comprising plasma treating the surface of the cell culture substrate prior to dispersing the diluted monomers on the surface of the cell culture substrate.

11. The method of claim 1 , wherein polymerizing the monomers comprises exposing the monomers to UV radiation.

12. The method of claim 11 , wherein exposing the monomers to UV radiation comprises exposing the monomers to pulsed UV radiation.

13. The method of claim 12 , wherein the pulsed UV radiation is delivered at a dose of between about 0.5 J/cm 2 and about 1.1 J/cm 2 at a power of between about 5 mW/cm 2 and about 100 mW/cm 2 .

14. The method of claim 12 , wherein exposing the monomers to pulsed UV radiation comprises exposing the monomers to radiation under nitrogen protection.

15. The method of claim 1 , further comprising washing the synthetic polymer layer with a solution comprising the solvent.

16. The method of claim 1 , wherein the one or more (meth)acrylate monomers are combinations of multi-functional and mono-functional (meth)acrylate monomers.

17. The method of claim 1 , wherein polymerizing the monomers on the surface of the cell culture substrate to form the synthetic polymer layer comprises forming a swellable (meth)acrylate layer.

18. The method of claim 17 , further comprising conjugating a polypeptide to the swellable (meth)acrylate layer.

19. The method of claim 1 , wherein one or more (meth)acrylate monomers comprises glycerol dimethacrylate.
