TEM images of PVA/ferritin nanofibers with a diameter of about deposited on a carbon coating grid: (a) a PVA/ferritin nanofiber containing uniformly dispersed ferritin and (b) a high magnification image of ferritin incorporated homogeneously within the polymeric matrix. The arrows indicate the core diameter of approximately .
(Color) (a) An AFM contact mode image of PVA and PVA/ferritin nanofibers oriented linearly on an AFM calibration grating with -wide periodic trenches, with the inset showing an AFM image taken at high magnification. The height profiles of a nanofiber taken along the direction of the dashed and solid lines shown in (a) are shown in (b) and (c), respectively.
(a) A schematic diagram of a nanofiber deflected by an AFM tip. (b) The force-displacement curves obtained on an AFM calibration grating as a reference (dashed line) and at the midpoint of a suspended nanofiber (solid line). The deflection of the nanofiber signifies the difference between the nanofiber and the reference curve.
The elastic modulus of PVA and PVA/ferritin nanofibers for . ( is the width of the , is the diameter of the measured nanofiber, and is the elastic modulus.)
