Abstract

The present invention relates to a microfluid-system-supporting unit, comprising a fixing layer formed on a substrate, a protective layer or a fixing layer, wherein part of at least one hollow filament in any shape is placed and fixed in the fixing layer. Thus, it provides a microfluid-system-supporting unit lower in surface irregularity even when there are multiple hollow filaments different in external diameter or the hollow filaments crosses each other and resistant to positional deviation of the hollow filament in the crossing regions, and a production method thereof.

Claims

1-32. -32. (canceled)

33. A method of producing a microfluid-system-supporting unit, comprising at least the following steps of:

(v) coating a particular region of a substrate with a varnish

(vi) immersing at least part of at least one hollow filament in the varnish or floating at least one hollow filament on the varnish, and

(vii) solidifying all or part of the varnish.

39. The method of producing a microfluid-system-supporting unit according to claim 33, further comprising a step of forming an intermediate layer on the substrate before coating a particular region of the substrate with the varnish.

41. The method of producing a microfluid-system-supporting unit according to claim 39, further comprising a step of placing all or part of the at least one hollow filament in any shape on the intermediate layer.

42. The method of producing a microfluid-system-supporting unit according to claim 39, wherein the intermediate layer is a layer having an adhering potential, a layer having a buffering potential, or a layer having a releasing potential.

43. The method of producing a microfluid-system-supporting unit according to claim 33, wherein a bank is formed and a particular region is covered with the varnish.

44. The method of producing a microfluid-system-supporting unit according to claim 39, further comprising a step of removing at least part of the intermediate layer after all or part of the varnish is solidified.

45. The method of producing a microfluid-system-supporting unit according to claim 33, further comprising a step of removing at least part of the substrate after all or part of the varnish is solidified.

46. The method of producing a microfluid-system-supporting unit according to claim 33, wherein the hollow filament is fixed in any shape and is immersed in the varnish or floated on the varnish.

47. The method of producing a microfluid-system-supporting unit according to claim 46, wherein the hollow filament is placed and fixed previously on the substrate or the intermediate layer of the substrate having it.

48. The method of producing a microfluid-system-supporting unit according to claim 33, wherein the hollow filament is fixed in any shape in the varnish.

49. The method of producing a microfluid-system-supporting unit according to claim 33, wherein the varnish is fluid.

50. The method of producing a microfluid-system-supporting unit according to claim 33, further comprising a step of removing the varnish.

34. The method of producing a microfluid-system-supporting unit, further comprising a step of:

(viii) forming a protective layer in a particular region.
