1. An automated method of forming an array of ligands on a support having localized areas comprising(a) locating a dispenser to dispense a solution a distance away from a surface of the support;
- (b) dispensing a first monomer in a volume of solution in a single coupling step of less than 5 nl onto the surface of the support to occupy a localized area smaller than 1 cm2;
(c) allowing the first monomer to attach directly or indirectly to the surface of the support at the localized area;
(d) repeatedly dispensing an additional group of added monomers in a volume of solution in a single coupling step of less than 5 nl at a same or different localized area in a manner to couple with a compound at one or more localized areas until an array of at least 100 different ligands, each at an individual localized area is formed and wherein density of localized areas on the support is at least about 1000 localized areas per cm2 of surface of the support.

Abstract
A method for producing polymer arrays by spacing a dispenser a distance from a surface of a support, dispensing a volume containing a monomer in a single coupling step of less than 5 nl to occupy a localized area of less than 1 cm2 of the surface of the support, allowing the monomer to bind directly or indirectly to the support and repeating the steps to produce an array of at least 100 polymer ligands at a density of 1000 per cm2 or greater.
