30th day of implantation of Au-PP-PEG-2000 (a) and Au-PP-PEG-4000 (b). (Mason’s Trichrome staining, 40x magnification.) The capsule is thicker with more inflammatory cells and newly formed blood vessels (thin arrow) in Au-PP-PEG-2000 (a), and neovascularization (thick arrow) and giant cell accumulation (thin arrow) is more prominent in histological section of Au-PP-PEG-4000 (b).
