Coating Copies Biosurfaces
UNIVERSITY PARK, Pa., Sept. 17, 2008 -- A thin coating of glass has been used to rapidly and inexpensively copy the micro- and nanostructure of biological surfaces to exploit properties such as light interaction, thermal ability and adhesion. The research could one day lead to cars with an insect-like metallic finish, or the deep black of a butterfly’s wing, with reflectors patterned after the nanostructure of a fly’s eyes, according to Penn State researchers who have developed the method.Butterflies, flies, flower...
