One class of biomimetic antifouling coatings is inspired by the surface of shark skin, which consists of nanoscale overlapping placoid scales that exhibit parallel ridges that effectively prevent sharks from becoming fouled even when moving at slow speeds. The antifouling qualities of the shark skin-inspired designs appear highly dependent upon ...
He discovered that shark skin denticles are structured in a characteristic diamond-repeating micro-pattern with millions of small ribs [3] at the micrometer scale. His mathematical model for the texture of a substance that would deter microorganisms from settling corresponds to the width-to-height ratio of shark denticle riblets.
Molded and laser-ablated shark skin replicas have been fabricated, and shown to be oleophobic in water. The molded replicas use a negative made of polyvinylsiloxane dental wax and the positive replica was made of epoxy. [55] These replicas have also shown that the structure of shark skin reduces the fluid drag caused by turbulent flow.

Artificial skin is a collagen scaffold that induces regeneration of skin in mammals such as humans. The term was used in the late 1970s and early 1980s to describe a new treatment for massive burns. It was later discovered that treatment of deep skin wounds in adult animals and humans with this scaffold induces regeneration of the dermis. [1]

The early horse-skin variety of equine-based faux-shagreen was traditionally prepared by embedding plant seeds (often Chenopodium) in the untreated skin while soft, covering the skin with a cloth, and trampling them into the skin. When the skin was dry, the seeds were shaken off, leaving the surface of the leather covered with small indentations.
