文摘

Molecular computation is fashionable because of the small device sizes that should be possible. For instance, information processing in nanospaces is widespread in biology. However, experimental cases with computing molecules occupy rather large volumes until now (ca. 10¹² nm³). Now we demonstrate small-scale computation using a designed logic gate in spheres of 3 nm radius (volume = ca. 10² nm³) which are produced by detergent micelles. The logic gate accommodated in the small nanospace fluoresces only when both H⁺ and Na⁺ ions are available.
