Small molecule microarrays
First Claim
1. A small molecule array which comprises a surface having affixed thereto or therein, in discrete, defined locations, one or more small molecules to be assessed for their effect(s) on one or more observable properties of a biological sample, wherein the small molecules are affixed to the surface by means of a polymer that immobilizes the small molecules to the surface, permits release of the small molecules, permits attachment of cells plated thereon or therein and is not toxic to cells plated thereon.

16. A small molecule-cell array which comprises:
- (a) a small molecule to be assessed for its effect on a phenotypic characteristic of cells and (b) cells on which an effect of the small molecule is to be assessed, wherein the small molecule is affixed to or within the surface of the array in discrete, defined locations by means of a polymer that immobilizes the small molecule to or within the surface, permits release of the small molecule and attachment of cells plated thereon or therein and is not toxic to cells plated thereon or therein and the cells are plated thereon or therein.

27. A method of producing a small molecule array, wherein the small molecule array comprises test small molecule-containing hydrogel spots arrayed on a surface, comprising:
- (a) arraying a test small molecule-hydrogel solution on or within a surface in discrete, defined locations, thereby producing a surface bearing or containing the test small molecule-hydrogel solution in discrete, defined locations and (b) subjecting the surface produced in (a) to conditions under which polymerization of the solution occurs, whereby the solution is polymerized and affixed to or within the surface as test small molecule-containing hydrogel spots, thereby producing the small molecule array.

33. A method of identifying a small molecule that has an effect on a phenotypic characteristic of cells, comprising plating the cells on or in a small molecule array, wherein the small molecule array comprises a surface having affixed thereto or therein, in discrete, defined locations, test small molecule-containing hydrogel spots, thereby producing a small molecule-cell array;
- maintaining the small molecule-cell array under conditions under which small molecule is released from the hydrogel spots and contacts membranes of vicinal cells;
observing effects of the small molecule on phenotypic characteristics of the vicinal cells, wherein if a phenotypic characteristic of vicinal cells is altered, the test small molecule is a small molecule that has an effect on a phenotypic characteristic of the cells. - View Dependent Claims (34, 35)
