Abstract

A microporous structure includes an array of nano wires and a coating about the nano wires of the array. The coating defines pores between the nano wires.

First claim

What is claimed is:

1 . An apparatus comprising:
an array of joined nano wires; and a coating about the nano wires, the coating defining pores between the nano wires to form a microporous structure.

2 . The apparatus of claim 1 further comprising an organic phase supported within the pores to form a supported liquid membrane.

3 . The apparatus of claim 1 further comprising a substrate joining the nano wires of the array.

4 . The apparatus of claim 3 , wherein the substrate comprises a channel containing the array of nano wires.

5 . The apparatus of claim 1 , wherein the coating joins the nano wires of the array.

6 . The apparatus of claim 1 , wherein the nano wires of the array are bent.

7 . A sample preparation device comprising:
a donor phase microfluidic channel; an acceptor phase microfluidic channel; and a supported liquid membrane between the donor phase microfluidic channel and the acceptor phase microfluidic channel, and supported liquid membrane comprising:
a microporous structure comprising:
an array of nano wires; and
a coating about the nano wires, the coating defining pores between the nano wires; and

an phase supported within the pores.

8 . A method comprising:
forming an array of nano wires upon a substrate; coating the nano wires of the array to form pores between the array of nano wires.

9 . The method of claim 8 , wherein the nano wires are coated such that coatings of different nano wires interconnect the different nano wires.

10 . The method of claim 8 further comprising adjustably controlling a thickness of the coating to adjustably control a size of the pores of the microporous structure.

11 . The method of claim 8 further comprising adjustably controlling a density of the array of nano wires upon the substrate to adjustably control a density of the pores of the microporous structure.

12 . The method of claim 8 further comprising adjustably controlling a density of the array of nano wires upon the substrate to adjustably control a size of the pores of the microporous structure.

13 . The method of claim 8 further comprising filling the pores within active phase to form a supported liquid membrane.

14 . The method of claim 8 , wherein the coating is applied while the nano wires are in a bent state.

15 . The method of claim 8 , wherein the forming of the array of nano wires comprises nano imprinting the nano wires.
