Representative TEM images exhibited different levels of structural alterations after 3 months of storage. (A-C) non-cross-linked and (D-F) RF0.5% cross-linked specimens. The specimens treated with a modified (D-F) RF0.5% adhesive exhibited well-preserved collagen fibril structure as pointed by white arrows. Specimens treated with a (G-I) RFLi0.5%/0.25% exhibited a thicker collagen network modified with the permeation enhancer exhibiting a well-preserved and compact collagen network as indicated by a dotted circle. Specimens that were treated with the permeation enhancer (J-L) RFLi0.5%/0.5% displayed a similar well-preserved thick structure of collagen fibrils with distinct collagen crossbanding (white arrows).
