Soft Tissue Response to the Presence of Polypropylene-G-Poly(ethylene glycol) Comb-Type Graft Copolymers Containing Gold Nanoparticles
Figure 2
Histological appearance of PP (a) and PP-PEG-4000 (b) polymers. (H&E staining, 40x magnification.) Notice thick capsule (C) around pure polypropylene sample compared to graft copolymer. New blood vessels (thick arrow) are in majority in PP, and giant cell (thin arrow) count is prominent in PP-PEG-4000.
