Abstract

Disclosed herein is a method of: treating an organic polymer with an electron beam-generated plasma; exposing the treated polymer to air or an oxygen- and hydrogen-containing gas, generating hydroxyl groups on the surface of the polymer; reacting the surface with an organosilane compound having a chloro, fluoro, or alkoxy group and a functional or reactive group that is less reactive with the surface than the chloro, fluoro, or alkoxy group; and covalently immobilizing a biomolecule to the functional or reactive group or a reaction product thereof.

First claim

What is claimed is:

1 . An article make by a method comprising:
treating a microtitre plate comprising an organic polymer and comprising a plurality of wells with an electron beam-generated plasma; exposing the treated polymer to air or an oxygen- and hydrogen-containing gas; wherein the treating and exposing generates hydroxyl groups on the surface of the polymer; reacting the surface with an organosilane compound having a chloro, fluoro, or alkoxy group and a functional or reactive group that is less reactive with the surface than the chloro, fluoro, or alkoxy group; and covalently immobilizing a biomolecule to the functional or reactive group or a reaction product thereof.

2 . The article of claim 1 ;
wherein the reaction product is made by reacting the organosilane compound with a crosslinker; and wherein the biomolecule is covalently immobilized to the crosslinker.

3 . The article of claim 2 , wherein the organosilane compounds in at least two different wells are each reacted with a different crosslinker.
