At first I was incredulous but after reading the reasons why, I say why not? Apparently, shark skin prevents deadly infections in humans; it carries dermal denticles to detach barnacles and algae. Underneath the dermal denticles lays a cushion that enables the shark to glide through water easier.
But what for?
Dr. Shravanthi Reddy, director of research for sharklet, replies
"This material could be an answer to the enormous problem of secondary infections in hospitals, using it in places and objects that are constantly touched - bedside tables, door panels. "Those wristbands, have you ever seen anyone clean those wristbands?" said Dr. Reddy. "Never, right? And they're on the patient the whole time they're in the hospital."
