This material enables specific binding to nucleic acids in solution under high-salt and low-pH conditions through hydrophobic interactions, hydrogen bonding, and electrostatic adsorption, while exhibiting negligible binding to other impurities such as proteins. It facilitates rapid isolation of nucleic acids from biological samples with straightforward and safe operation, and is well-suited for automated and high-throughput nucleic acid extraction workflows, making it ideal for modern genomics and diagnostic applications
