(PANI) and anatase TiO 2 nanoparticles (NPs) is presented. The presence of sulfonated
polystyrene (SPS) affects the polymerization reaction. Horseradish peroxidase (HRP) was
used to catalyze the polymerization. Polyaniline was deposited on the surface of TiO 2 NPs,
forming a core-shell structure. Enzymatically synthesized nanocomposite was characterized
by FT-IR spectroscopy, UV-Vis. spectroscopy and scanning electron microscopy (SEM). The …
