Fabrics are treated with a film-forming material and a blowing agent, typically ammonium carbonate or bicarbonate, and ironed. The fabrics thus acquire dry wrinkle resistance, in addition to the benefit provided by the film-forming material.

In the examples set forth herein, nucleic acid extraction materials are capable of selectively extracting cell free nucleic acids, including cell free DNA, directly from whole blood samples or plasma. Also included are methods of making and using the nucleic acid extraction materials. One example of a nucleic acid extraction material includes a substrate. This example of the nucleic acid extraction material also includes a polycation bonded to at least a portion of a surface of the substrate. In this example, the polycation consists of a polymer of a quaternized monomer selected from the group consisting of a quaternized 1-vinylimidazole monomer and a quaternized dimethylaminoethyl methacrylate monomer, or a copolymer of a neutral monomer and the quaternized monomer.
