Figure 4From: Development of biodegradable polycaprolactone film as an internal fixation material to enhance tendon repair: an in vitro study FESEM images of the tendon outer membrane and biofilm cross-section. (A) The pores of rabbit Achilles tendon outer membrane had diameters from 1 to 9 μm. (B) The pores of the cross-section of the biofilm had diameters from 4 to 12 μm. Three randomly chosen fields of view were photographed from each specimen. Representative images are shown.Back to article page
