Schematic representation of chirality-induced wettability switching on a chiral smart polymer film containing the β-Asp-Phe-dipeptide chiral recognition unit. (a) Molecular interaction models of the Asp-Phe-dipeptide with L- or D-lyxose. (b) Shrunken and swollen states of polymer films induced by treatment with L- or D-lyxose solution. (c) Chirality-induced macroscopic wettability discrimination on the polymer film, which was amplified by the structured effect of a textured substrate. Adapted from Qing and Sun76 (2011 Wiley-VCH).
