SEM image of the fiber, (c) a wound prior to dressing with the borate glass nanofiber,

Figure 6.11
A chronic heel wound treated with borate glass nanofiber. Prior to
treatment, the wound had existed for two years.
The patient had the wound for over two years, was a diabetic, and in rela-
tively poor health. After approximately one month of treatments with the
borate glass fibers administered twice per week, the wound had resolved.
A second example is a venous stasis ulcer on the upper leg of an obese
woman in relatively poor health (prediabetic). The wound (Figure 6.12)
was initially presented with a strong odor (likely a yeast infection) and
