Parallel production of high density arrays

A method for detection of compounds on an array by:

• a. immobilizing binding compounds onto rod shaped array elements;
• b. forming a bundle of the rod elements using a guide to create a spatially uniform arrangement of rod elements and securing with a sheath material;
• c. cutting individual arrays from the bundle to generate a multiplicity of binding surfaces and fixing or placing one side of the array to an absorbent pad;
• d. applying a sample to the surface of an array and allowing the sample to flow through the porous rod elements of the array into the absorbent pad;
• e. exposing and developing the array;
• f. correlating the binding pattern of the binding surfaces with the composition of elements in the array.

A method of detecting components in a sample mixture or detection of compounds on an array by:

• a. forming lines of immobilized binding compounds on a sheet of material, wherein lines of binding compounds maybe separated by identification marks, and the binding material is impregnated into the thickness of the sheet material;
• b. rolling the printed sheet into spiral wound structure about a rod and securing roll with a sheath;
• c. cutting individual arrays from the bundle to expose binding elements formed by the freshly exposed edge of sheet material separated by identification marks and interstitial space between adjacent membrane layers, and fixing or placing one side of the array onto an absorbent pad;
• d. exposing and develop the array;
• e. correlating the binding pattern on the array with the composition of the binding elements.

A method of detecting components in a sample mixture or detection of compounds on an array by:

• a. synthesizing of binding compounds onto rod shaped array elements using a randomized method;
• b. marking the identification of each rod at each synthesis step by spin coating with paint;
• c. forming a bundle of the rod elements and securing with a sheath material;
• d. exposing and developing the array;
• e. correlating the binding events with the identification marks.

A method of detecting components in a sample mixture or detection of compounds on an array by:

• a. immobilizing binding compounds onto rod shaped array elements;
• b. forming a bundle of the rod elements and securing with a sheath material so that rod elements treated with a given binding agent are grouped to create a graphic symbol/s surrounded by rod elements with different or substantially no affinity for components in the test sample;
• c. cutting individual arrays from the bundle and fixing or placing one side of the array to an absorbent pad;
• d. exposing and developing the array;
• e. correlating the graphic symbol/s with the presence or absence of analyte(s).
