Controlling the degree of twist in nanostructured particles for the first time

"precisely controlled micron-sized bow ties produce materials interact with twisted light, providing new tools for machine vision and producing medicines... can engineer degree of twist without breaking a structure like DNA... Twisted structures encode information in shapes of light waves reflecting from surface, rather than in 2D arrangement of symbols that comprises most human-read signs... preferentially reflect certain kinds circularly polarized light, shape that twists as moves through space"
