Description
Summary:Superhydrophilicity In article number 2100844, Jungbae Kim, Young Keun Kim, and co‐workers present an inorganic‐organic heterostructure (IOH) mimicking the shape of sea urchin, which consists of zinc oxide nano‐spicules and polylactic acid microfibers and microbeads. The sea urchin‐like topography of the IOH induces superhydrophilicity that effectively enhances the bactericidal activity of both gram‐positive and gram‐negative bacteria by allowing zinc oxide nanospicules to be in contact with the bacterial surface.
