Oxidized styrenic polymers for DNA binding
First Claim
1. A method of immobilizing DNA to a surface consisting essentially of:
- a) providing a styrenic polymer substrate having a surface oxygen content of between 0.2 and 8.0 atomic percent, and b) attaching at least one aminated DNA molecule directly to the surface of the substrate, said aminated DNA molecule comprising a primary amine attached to a terminal end of a DNA molecule via a linker arm.

Abstract
A method of immobilizing aminated DNA to a substrate surface is provided for use in DNA hybridization assays. The surface can be widely employed in a variety of molded laboratory products including multiwell plates, cell culture dishes, and biological containers. The method comprises the steps of providing a polystyrene substrate having a surface content of between 0.3 and 4.0% atomic percent oxygen, and attaching amine modified oligonucleotide to the surface of the substrate. A resultant product comprising a polystyrene substrate having a surface oxygen content of between 0.3 and 4.0% atomic percent, and a plurality of amine modified oligonucleotides directly attached to the surface of the substrate, is also disclosed.
