鯊魚

????佛羅里達(dá)大學(xué)（University of Florida）的一位教授發(fā)現(xiàn)，鯊魚皮膚上的菱形顯微結(jié)構(gòu)能夠抑制海洋細(xì)菌附著。現(xiàn)在，科羅拉多州奧羅拉的Sharklet Technologies公司對(duì)鯊魚皮膚的數(shù)學(xué)圖形進(jìn)行了模擬，研制出了一種抗菌薄膜，可應(yīng)用于醫(yī)療設(shè)備和醫(yī)院設(shè)施臺(tái)面。根據(jù)病原體的不同，這種薄膜可減少90%至99%的細(xì)菌。

Sharks

????A University of Florida professor discovered that the tiny microscopic diamond-shape patterns on a shark's skin actually allow the animal to stay free of marine bacteria. Now Sharklet Technologies in Aurora, Colo., mimics those mathematical patterns to create antibacterial surface textures for medical devices and hospital countertops. Depending on the pathogen, the textures can cut bacteria by 90% to 99.9%.
