Abstract

In one embodiment of the invention, there is provided a kit including: (i) a plasma polymerized surface having first and second regions, said first region including a first concentration of carboxylic acid groups on said plasma polymerized surface and said second region including a second concentration of carboxylic acid groups on said plasma polymerized surface, wherein said first concentration and said second concentration are different; (ii) a first plasma polymerized secondary substrate having carboxylic acid groups disposed consistently thereacross at a concentration equal to said first concentration; and, (iii) a second plasma polymerized secondary substrate having carboxylic acid groups disposed consistently thereacross at a concentration equal to said second concentration.

Claims (10)

1. A kit comprising:

i) a plasma polymerized surface having first and second regions, said first region comprising a first concentration of carboxylic acid groups on said plasma polymerized surface and said second region comprising a second concentration of carboxylic acid groups on said plasma polymerized surface, wherein said first concentration and said second concentration are different;

ii) a first plasma polymerized secondary substrate having carboxylic acid groups disposed consistently thereacross at a concentration equal to said first concentration; and,

iii) a second plasma polymerized secondary substrate having carboxylic acid groups disposed consistently thereacross at a concentration equal to said second concentration.

2. The kit of claim 1 , wherein said first region comprises a concentration of carboxylic acid groups from 2% to 11%.

3. The kit of claim 1 , wherein said second region comprises a concentration of carboxylic acid groups from 2% to 11%.

4. The kit of claim 1 , wherein said plasma polymerized surface having first and second regions comprises a known amount of polymer deposited on said surface.

5. The kit of claim 1 , wherein said plasma polymerized surface comprises plasma deposited gradients of octadiene to acrylic acid.

6. The kit of claim 5 , wherein said plasma polymerized surface comprises a known amount of octadiene and acrylic acid deposited in each of said first and second regions.

7. The kit of claim 6 , wherein the amount of octadiene and acrylic acid deposited in each of said first and second regions is variable.
