1. A method for detecting a target biopolymer in a sample, comprising:
- (a) preparing a microarray of said sample by dispensing aliquots of said sample at discrete sites onto a substrate and immobilizing said target biopolymer on said substrate, wherein the microarray is an array of dots, each dot having a diameter from about 1 to 500 microns, wherein each of said aliquots contains the same amount of said target biopolymer;
(b) contacting said microarray with one or a plurality of probe biopolymers under conditions that allow the formation of one or a plurality of complexes, each complex comprising said target biopolymer and one of said probe biopolymers, wherein said probe biopolymers are dispensed on said dots in said microarray; and
(c) detecting the presence of and quantifying said complexes as a measurement for the presence or the amount of the target biopolymer in said sample.

Abstract
The present invention is directed to the production of a sample microarray for use in detecting one or more target biopolymers in the sample. The sample microarray of this invention is formed by distributing equivalent amounts of a single sample at discrete, spatially defined locations on a substrate. Each site in the microarray, thus, has the same composition of target biopolymers. The microarray is then interrogated by one or more probes specific for one or more the target biopolymers.
