Magnetically modified electrospun nanotextile exhibiting peroxidase-like activity

The magnetic modification of four different electrospun nanofibrous textiles, based on polyamide, polyvinyl alcohol, polycaprolactone and polyurethane, is reported. The simple spray modification procedure employing two types of magnetic fluids was used. Magnetic modification led to the deposition of magnetic iron oxide nanoparticles on the surface of textile nanofibers. Magnetic nanotextile exhibited response to external magnetic field and was stable for a long time. Magnetic modification has not substantially changed the structure of the modified nanotextile. Magnetically modified nanotextile exhibited peroxidase-like activity and thus it represents a promising composite material applicable in various biochemical, biomedical and biotechnology applications.
