Patent ID: 7105340

Claim:
A method for preparing an on-spot selectively activated hydrophobic slide, comprising the steps of: preparing a hydrophobic copolymer in a solvent to obtain a solution of hydrophobic copolymer; wherein the hydrophobic copolymer is prepared by co-polymerization of a hydrophobic material and a compound bearing a functional group protected by a protecting group to form an inactive copolymer; wherein the functional group is an imide or a cyclic amide; and wherein the protecting group is a photo acid group; coating the solution of the inactive copolymer of the hydrophobic copolymer onto a substrate; removing the solvent; and selectively photolithographically activating areas of the inactive copolymer of the hydrophobic copolymer with light to remove the protecting group of the inactive copolymer so as to convert the areas of the inactive copolymer of the hydrophobic copolymer into a functionally active copolymer.
