Background: Though there are many patents on silk, patents on sea silk are rare. Sea silk is one of the most coveted materials in the world, and the technology to make sea silk is at an extremely high risk of extinction. Unlike spider dragline silk and silkworm silk, this natural silk has been forgotten in the academic commune for millennia, though it has many fascinating properties: high strength, remarkable adhesion, extreme lightweight, and others.

Methods: Here we report that mussel-derived silk fibers can be fabricated by electrospinning. Instead of extracting proteins from byssus, we directly use the protein solution from alive blue mussels, which are intensely commercially used. The protein solution and the polyvinyl alcohol solution are mixed together to produce mussel-based silk fibers.

Results: The mussel-based silk fibers have many special properties like high mechanical strength, remarkable super-contraction and good wetting properties.

Conclusion: The electrospinning mussel-based silk fibers have the potential for use as a replacement for the rarest sea silk and as a new bio-inspired material with multi-functions.

背景：尽管丝绸的专利很多，但海丝的专利却很少。海丝是世界上最令人垂涎​​的材料之一，制造海丝的技术面临着极高的灭绝风险。与蜘蛛拉丝和蚕丝不同，这种天然蚕丝虽然具有许多引人入胜的特性：高强度，出色的附着力，极轻的特性等，但它已在学术界被遗忘了数千年。

方法：在这里我们报告说，贻贝衍生的丝纤维可以通过静电纺丝来制造。除了直接从罐中提取蛋白质外，我们还直接使用鲜活的蓝贻贝中的蛋白质溶液，后者在商业上已大量使用。将蛋白质溶液和聚乙烯醇溶液混合在一起以生产基于贻贝的丝纤维。

结果：贻贝基丝纤维具有许多特殊性能，如高机械强度，出色的超收缩性和良好的润湿性。

结论：静电纺贻贝基丝纤维有潜力替代最稀有的海丝，并成为一种具有多种功能的新型生物启发材料。
