Synthesis and characterization of polyaniline/ graphene composite nanofiber and its application as an electrochemical DNA biosensor for the detection of mycobacterium tuberculosis

This article describes chemically modified polyaniline and graphene (PANI/GP) composite nanofibers prepared by self-assembly process using oxidative polymerization of aniline monomer and graphene in the presence of a solution containing poly(methyl vinyl ether-alt-maleic acid) (PMVEA). Characterizat...
