Sessile organisms have undergone long-term evolution to develop the unique ability by positioning themselves on wet solid surface through secreting adhesive proteins. The present study reveals that natural amino acid monomers can also exhibit similar adhesion capacity. This kind of biomimetic adhesives were created by the one-step aqueous assembly of basic amino acids with assistance of anionic polyoxometalates. The polyoxometalates not only serve as multivalent scaffold to initiate the supramolecular cross-linking of amino acid molecules, but also function as a redox component, bestowing the wet adhesives with electrochromic features.
无柄生物通过分泌黏附蛋白，长期进化出了在湿固表面定位自身的独特能力。本研究揭示了天然氨基酸单体也具有类似的黏附能力。这种仿生黏附剂是通过在多酸阴离子的协助下，由碱性氨基酸一步水相组装而成。多酸不仅作为多价支架来引发氨基酸分子的超分子交联，还作为氧化还原组分，赋予湿黏附剂电致变色特性。
