Self-assembled NiFe2O4/carbon nanotubes sponge for enhanced glucose biosensing application

- Self-assembled NiFe2O4/CNTs sponge was prepared by ice-templating method.
- The mechanism of NiFe2O4 modified CNTs relied on π-π interactions and static cling.
- The porous structure made for GOx load, electrons transport and reactants diffusion.
- Double catalysis and enhanced glucose sensing were achieved with elements Ni and Fe.
