Figure 5

LN-LSMA, 37 days (a) electrode tip with thin film of encapsulation tissue, scale 10 μm. (b) Platinum/parylene interface without delamination, scale 1 μm. (c) The platinum/parylene interface of another electrode at a different angle showing no significant delamination and a thin layer of fibrosis, scale 2 μm. (d) Intact platinum electrode tip partially covered with encapsulation tissue approx. 250 nm thick, scale 2 μm. (e) Active macrophages and fibroblasts along the base of the array, scale 100 μm. (f) Close-up at base of electrode from (e) showing active tissue growth (and an erythrocyte), scale 5 μm. (g) Higher magnification of encapsulation tissue from (f) showing individual collagen fibers, scale 200 nm. All images in this figure were taken at 5 kV.
