Lithographic columns

The positioning of fibrils between the lithographic columns was made specific through the use of both noncovalent and covalent chemistry shown in Figure 16. Dinca first deposited a layer of photobiotin on the column surface, this layer was then exposed to ultraviolet light in order to activate... 

It is interesting, first of all, to explore some interesting phenomena in the lithograph, which is a visual shock. The columns appearing in the picture can be seen as either concave or convex. On the right-hand side, the solid floor underfoot...
