This article argues that feminist technoscience studies can enrich our understanding of biopolitics by challenging the body’s boundaries and focusing on mundane practices of security. To do so, this article looks to Mexicanas/os who cross the US–Mexico border in order to donate plasma in the United States. The article argues that Mexicanas/os are objectified in cross-border donation practices as both desirable sources of life-giving matter and dangerous sources of disease. The article begins by giving some empirical context to plasma donation, before outlining the conceptual contributions of a feminist technoscience studies approach. The article then explores how Mexican bodies are produced as sites of valuable matter which have the ability to make others live. The article shows how the ‘bioavailability’ of Mexicanas/os is produced through colonial and racist histories. Finally, the article turns to the circulation of plasma, demonstrating how persistent fears about Mexican plasma as infectious reproduce highly racializing stereotypes about Mexico and Mexican bodies. The article finishes by reflecting on the importance of a feminist technoscience studies approach for stressing the co-constitutive relationship between race and matter, and that racialized productions of the body at security sites stretch well beyond the body’s skin.

边境血浆捐赠：女权主义技术科学、身体和种族

本文认为，女权主义技术科学研究可以通过挑战身体的界限和关注世俗的安全实践来丰富我们对生命政治的理解。为此，本文着眼于跨越美墨边境以在美国捐赠血浆的墨西哥人/其他人。这篇文章认为，墨西哥人 / os 在跨境捐赠实践中被客观化为生命物质的理想来源和疾病的危险来源。本文首先给出了血浆捐赠的一些经验背景，然后概述了女权主义技术科学研究方法的概念贡献。然后，文章探讨了墨西哥的尸体是如何作为有价值的物质的场所生产的，而这些物质有能力让其他人生活。这篇文章展示了墨西哥人 / os 的“生物利用度”是如何通过殖民和种族主义历史产生的。最后，文章转向血浆的流通，展示了对墨西哥血浆具有传染性的持续恐惧如何再现对墨西哥和墨西哥身体的高度种族化的刻板印象。文章最后反思了女性主义技术科学研究方法在强调种族与物质之间的共同构成关系方面的重要性，以及在安全场所种族化的身体生产远远超出身体的皮肤。
