  • Figure 1. A typical DMT modulus calculation output of the NanoScope Analysis software. Each DMT modulus map was analyzed at least using three cross sections across the modulus map
  • Figure 2. AFM DMT modulus images. High magnification DMT modulus images of the fiber surface clearly shows morphological appearance of the two, Ag and ZnO nanoparticles in micrograph. (a) Non-coated background fiber mat; (b) 30:30 (Ag:ZnO) sputtered fiber mat; (c) 100:30 (Ag:ZnO) sputtered fiber mat; (d) 30:100 (Ag:ZnO) sputtered fiber mat
