Figure 4
Scanning electron micrographs of the Medpor implant: (a) and (b) ×50 images; (b′) image in the (b) image is ×500 image of (b). (a) Image includes the section of original Medpor and (b); (b′) images include the section of Medpor plates treated with chitosan. The (b) image shows a smooth surface made of chitosan and the (b′) image shows the root part of a columnar structure made of chitosan.
