Abstract

See full text

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.
