Abstract: A disclosed polymer thin film includes a cationic polymer having a hydrolyzable side chain. The polymer thin film has a surface potential of 1 mV to 50 mV. A hydrolysis efficiency of the cationic polymer is 30% or more after reaction at 50° C. for one hour. The cationic polymer is dissolved to three-dimensionally capture nucleic acids, and releases the nucleic acids through hydrolysis. Thus, nucleic acid capturing-releasing efficiency can be improved.
