What does the shark’s skin do to bacteria?
The shark skin surface without nanoparticles reduced the attachment of E. coli by 70 percent compared to smooth films. But shark skin surfaces with TiO2 nanoparticles exposed to UV light for one hour killed off over 95 percent of E. coli and 80 percent of Staphylococcus aureus.
What is unique about shark skin?
Great White Sharks are stealthy hunters and the secret is in their skin. Shark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These denticles decrease drag and turbulence, allowing the shark to swim faster and more quietly.
Why is shark skin so Sandpapery?
Shark skin is made of a matrix of tiny, hard, tooth-like structures called dermal denticles or placoid scales. These structures are shaped like curved, grooved teeth and make the skin a very tough armor with a texture like sandpaper.

How shark scales unique design could stop bacteria spread?
Their shape and alignment reduce drag, stop algal attachment and can even kill prey. But now humans are using that same design to save lives. Sharklet’s material is able to inhibit bacteria growth and even limit touch transfer of viruses, reducing the transmission of harmful microorganisms.
Can shark skin be used?

How does shark skin reduce drag?
The skin of fast-swimming sharks protects against biofouling and reduces the drag experienced by sharks as they swim through water. The tiny scales covering the skin of fast-swimming sharks, known as dermal denticles (skin teeth), are shaped like small riblets and aligned in the direction of fluid flow (figure 1).
Does shark skin feel like sandpaper?
Shark skin feels similar to sandpaper.
Shark skin feels exactly like sandpaper because it is made up of tiny teeth-like structures called placoid scales, also known as dermal denticles. These scales point towards the tail and help reduce friction from surrounding water when the shark swims.

What makes the shark skin so different from bony fish skin?
Cartilagenous fish, like sharks and rays, have a different type of outer covering than bony fish. Their tough skin is covered with placoid scales – small, spiny, irregular-shaped scales called dermal denticles (“skin teeth”).
Is shark skin used for leather?
According to the FAO, there are about 25 shark species whose skin is desirable for producing leather. Of those only two, the Tiger Shark and Bull shark are near threatened. The others are vulnerable, endangered or critical.
Can shark skin be made into leather?
In fact, a single full-sized Grade III or IV shark skin could easily produce enough leather to make two or three belts. The leftover scraps from the belt cuts could be used to fill in patches on other exotic leather projects, or to make wristbands, tongues for shoes, and decorative tassels.
