Monodispersed Fe_3O_4/polypyrrole (PPy)hollow particles were synthesized via controllable in-situ deposition and polymeriza- tion techniques using poly(styrene-co-acrylic)(PSA)latex as template.Field-dependent magnetization plot illustrates that the capsules are superparamagnetic at 300 K.FTIR spectrum confirms that the myoglobin (Mb)molecule adsorbed on the surface of Fe_3O_4/PPy hollow particle essentially retains its native structure.Furthermore,direct electrochemistry of Mb can be realized on Fe_3O_4/PPy capsules modified pyrolytic graphite disk electrode,which indicates that the magnetic conductive polymer capsules can promote the electron transfer of protein.
Monodispersed Fe_3O_4 hollow particles were synthesized via controlledlable in-situ deposition and polymeriza- tion techniques using poly (styrene-co-acrylic) (PSA) latex as template. Field-dependent magnetization plot showing the capsules are superparamagnetic at 300 K. FTIR spectrum confirms that the myoglobin (Mb) molecule adsorbed on the surface of Fe_3O_4 / PPy hollow particle essentially retains its native structure. Future Electrochemistry of Mb can be realized on Fe_3O_4 / PPy capsules modified pyrolytic graphite disk electrode, which indicates that the magnetic conductive polymer capsules can promote the electron transfer of protein.
