Patent ID: 6849462

Claim:
A method of forming an array of polymers on a support having one or more localized areas comprising (a) depositing a resist onto a surface of the support; (b) selectively removing a portion of the resist to expose one or more localized areas; (c) dispensing a first monomer onto the surface of the support at the one or more localized areas wherein the one or more localized areas are smaller than 1 cm 2 ; (d) allowing the first monomer to attach directly or indirectly to the surface of the support at the one or more localized areas; (e) repeating steps (a) and (b) and then dispensing an additional group of added monomers onto the surface of the support at the one or more localized areas in a manner to couple with a compound at the one or more localized areas until an array of at least 10 different polymers at different localized areas is formed.
