Here, we report a high-throughput method for fabricating chiral copper surfaces via curved-surface confinement recrystallization. This approach exploits curvature-driven abnormal grain growth to transform polycrystalline foils into large-area crystals with continuously graded high-index surfaces. Systematic control of the curvature during annealing enabled the creation of a library of chiral copper surfaces, providing high-throughput and surface templates with defined chirality. Through manipulation of the initial crystal orientation and curvature, single crystals with tailored surface orientations can be reached. The intrinsic chirality of these surfaces is confirmed by circular dichroism spectroscopy and model asymmetric reactions. Furthermore, we demonstrate the transfer of chirality to epitaxial two-dimensional materials, exemplified by the growth of chiral graphene. This work provides a scalable platform for producing designer chiral surfaces, enabling future advances in asymmetric catalysis and chiral device engineering.<\/jats:p>","DOI":"10.1038\/s41467-026-69862-7","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T16:56:05Z","timestamp":1771606565000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High-throughput chiral copper foils by curved-surface confinement recrystallization"],"prefix":"10.1038","volume":"17","author":[{"given":"Deping","family":"Huang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhancheng","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinwu","family":"Duan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongna","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaxing","family":"Dong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2723-7724","authenticated-orcid":false,"given":"Guilin","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4635-6112","authenticated-orcid":false,"given":"Xiaoxu","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leining","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9153-9279","authenticated-orcid":false,"given":"Feng","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6083-2752","authenticated-orcid":false,"given":"Haofei","family":"Shi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,2,20]]},"reference":[{"key":"69862_CR1","doi-asserted-by":"publisher","first-page":"3158","DOI":"10.1021\/jp0041508","volume":"105","author":"GA Attard","year":"2001","unstructured":"Attard, G.
