荷兰设计师Iris van Herpen在巴黎高级定制时装周上发布了一件引人注目的生物发光裙，该裙子融合了前沿科技与时尚。这件裙子由1.25亿个活藻类构成，与生物设计师Chris Bellamy以及阿姆斯特丹大学的生物物理学家合作完成。裙子的发光原理源于藻类的生物发光现象，通过机械应力刺激发光。研究人员将藻类融入凝胶基质，使其在形变和运动时发光，同时保持藻类的活性。这件“活的”服装是Van Herpen新系列Sympoiesis的一部分，展示了科技与时尚的创新结合。

✨ 这件生物发光裙由Iris van Herpen设计，是其Sympoiesis系列的一部分，在巴黎高级定制时装周上首次亮相。裙子设计融合了时尚与生物科技，展示了设计师对创新材料和技术的探索。

💡 该裙子的核心在于其生物发光特性，这源于其中包含的1.25亿个单细胞生物发光藻类，学名为Pyrocystis lunula。这些藻类通过化学反应产生光，形成独特的视觉效果。

🔬 研究人员通过结合显微镜和机械测试，研究了藻类对机械应力的反应。他们建立了数学模型来描述光产生机制，并将藻类整合到凝胶基质中，使其在形变和运动时发光，同时保持藻类的活性。

🤝 该项目的成功离不开多方合作，包括设计师Iris van Herpen、生物设计师Chris Bellamy以及来自阿姆斯特丹大学和加州大学圣迭戈分校的生物物理学家和研究人员。这种跨学科的合作是实现创新设计的关键。

Fashion designer Iris van Herpen has unveiled a bioluminescent dress that features 125 million living algae. The garment involved Herpen collaborating with Biodesigner Chris Bellamy as well as biophysicists Nico Schramma and Mazi Jalaal from the University of Amsterdam.

Bioluminescence is the production of light by a living organism, caused by a chemical reaction such as the molecule luciferin reacting with oxygen.

The bioluminescent dress is composed of a gel material that incorporates millions of single celled bioluminescent algae of the species Pyrocystis lunula, named after their moon-like shape.

In the wild, the bioluminescent algae emit light as a defence mechanism. The flash serves as a warning signal that attract secondary predators, which hunt the main predator of the cells.

In 2019, Jalaal, Schramma and colleagues began to study how the cells respond to mechanical stresses. By combining microscopy and mechanical tests, they were able to measure the light-emission of the cells and how it depended on deformation, which led to a mathematical model that described the light-production mechanism (Phys. Rev. Lett. 125 028102).

The researchers then worked with Chenghai Li and Shengqiang Cai at the University of California San Diego and bioluminescence researcher Michael Latz from the Scripps Institution of Oceanography in San Diego.

They incorporated the cells in a gel matrix to create a flexible yet resistant substance that emits light upon deformation and movement while at the same time keeping the cells alive.

Bellamy and van Herpen developed and refined the bioluminescent material and incorporated it into a spectacular “living” garment, which on Monday was part of van Herpen’s new fashion collection – Sympoiesis – and unveiled at Paris Haute Couture Week.
