Polyvinyl alcohol PVA nanofibers containing bimolecular ferritin nanoparticles exhibited the
enhancement of elastic modulus as compared to pure PVA nanofibers due to chemical interactions
between the ferritin and the PVA matrix. The elastic modulus of the nanofibers was measured using
a three-point bending test employing an atomic force microscope AFM. To improve the reliability
of the AFM measurements, uniform nanofibers were oriented linearly on an AFM calibration grating
by introducing parallel subelectrodes in an electrospinning system. The length to diameter ratio of
the measured nanofibers was 16. The PVA nanofibers reinforced by ferritin are applicable as
artificial muscles and actuators.
