Polyanilie based nanomaterials and which were magnetically separable have been used for the immobilization of enzymes for recovery and recycle. Polyaniline nanomaterials which mixed with iron oxide nanoparticle were shown distinctive differences in morphology and revealed aggregated shapes. BET surface area was 46.36m2 g-1 decreased with the nanoparticle addition from 58.37m2 g-1. The magnetically separable catalase enzymes were developed using cross linked enzyme aggregation on the surface of nanomaterials. Developed nanoenzymes were used for the bioconversion of hydrogen peroxide and were successfully recovered with magnet and used repeatedly for reaction. The residual activity after 5 times reuse was 88% of its original activity.
