2D mussel‐inspired polydopamine (PDA) nanosheets are prepared and exploited as a functional surface for grafting various polymer brushes. The PDA nanosheet and its polymer‐brush derivatives show lateral integrity and are robust; therefore, they can be detached from their substrates. Cell‐adhesion tests show that the PDA nanosheet promotes cell growth and attachment, while a PDA‐based poly(3‐sulfopropyl methacrylate) carpet exhibits nonfouling behavior.

贻贝启发的聚合物地毯：聚合物刷在聚多巴胺纳米片上的直接光接枝，以控制细胞的粘附

制备了二维贻贝启发式聚多巴胺（PDA）纳米片，并将其用作接枝各种聚合物刷的功能性表面。PDA纳米片及其聚合物刷衍生物表现出侧向完整性，并且坚固耐用。因此，它们可以从其基底上分离。细胞粘附力测试表明，PDA纳米片促进细胞生长和附着，而基于PDA的聚（甲基丙烯酸3-磺丙酯）地毯表现出无污垢行为。
