摘要：
Disclosed is a process for retrieval of nucleotide sequence. The process includes mixing iron chloride tetrahydrate with iron (III) chloride hexahydrate in solution adding ammonium hydroxide to the mixture and stirring to form maghemite nanoparticles stirring the maghemite nanoparticles in a solution with an inorganic acid, a surfactant and a monomer precursor of a conducting polymer initiating polymerization of the monomer by adding the inorganic acid and an oxidizing agent to the stirred solution and further stirring to yield Polyaniline/maghemite nanocomposites adding the nanocomposites to an first aqueous solution of the nucleotide sequence and stirring so as to electrostatically interact the nanocomposites with the nucleotide sequence and weakening the electrostatic interaction between the nanocomposite and the nucleotide sequence to recover the nanocomposite independently of the nucleotide sequence.
