The study found that surfaces with the micropattern retained 94% less antibiotic resistant bacteria than an ordinary smooth surface. In the past, health officials have considered installing copper surfaces, which kills some bacteria. The study found that copper surfaces reduced bacteria by 80%. In a press release, Ethan Mann, a researcher for the maker of the product, said the micropattern would be manufactured as a part of typical plastic surfaces in hospitals including “environmental surfaces” and “medical devices.” “Sharklet does not introduce new materials or coatings – it simply alters the shape and texture of existing materials to create surface properties that are unfavorable for bacterial contamination,” he said. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3393737/bumpy-surfaces-disease-transmission/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3393737/bumpy-surfaces-disease-transmission/"},"headline":"Bumpy, Shark-Like Surfaces Could Lessen Disease Transmission","datePublished":"2014-09-17T17:28:21.000Z","dateModified":"2026-02-21T10:14:35.685Z","description":"Bacteria doesn't stick to the sharky material","url":"https://time.com/3393737/bumpy-surfaces-disease-transmission/","keywords":["Research","Technology","hospitals","health","Infectious Disease","Bacteria"],"thumbnailUrl":"","author":[{"@type":"Person","name":"Justin Worland","jobTitle":"Senior Correspondent","url":"https://time.com/author/justin-worland/"}],"articleSection":"Health","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/research/","name":"Research"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3393737/bumpy-surfaces-disease-transmission/","name":"Bumpy, Shark-Like Surfaces Could Lessen Disease Transmission"}}]}] ```
