Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
What is claimed is: 1. A method comprising: treating an organic polymer microtitre plate with an electron beam-generated plasma; exposing the treated plate to air or an oxygen- and hydrogen-containing gas; wherein the treating and exposing generates hydroxyl groups on the surface of the plate. 2. The method of claim 1 ; wherein the plasma is generated in argon; wherein the argon gas pressure is 90 mTorr+/10%; wherein the treatment time is 2 min+/10%; wherein the electron beam is pulsed at 50 Hz+/−10%; and wherein the electron beam is operated with pulse width of 2 ms+/−10%.
