Here, we show that polymer molecules end\u2010grafted to the surface of penta\u2010twinned gold nanorods (AuNRs) perform as active interfacial regulators controlling defect\u2010selective oxidative metal etching. Through a combination of experiments and simulations, we show that polymer brushes localize etchant ions on the AuNR surface, lowering the energetic barrier for Au atom removal at defect\u2010rich regions. This defect\u2013ligand interplay leads to the emergence of surface corrugations along the AuNR longitudinal facets, in stark contrast to the etching behavior of single\u2010crystal AuNR counterparts. By varying polymer molecular weight and grafting density, we achieve precise control of the plasmonic properties of etched AuNRs. These findings establish polymer brushes as active modulators of nanoscale interfacial reaction pathways, providing a strategy for defect\u2010directed nanoengineering with applications in catalysis, sensing, and photonics.<\/jats:p>","DOI":"10.1002\/anie.8508304","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T12:18:28Z","timestamp":1785327508000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Polymer Brushes Govern Defect\u2010Selective Oxidative Etching of Penta\u2010Twinned Gold Nanorods"],"prefix":"10.1002","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-7988-6241","authenticated-orcid":false,"given":"Tianyi","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Toronto  Toronto Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina","family":"Koriakina","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Toronto  Toronto Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9914-1142","authenticated-orcid":false,"given":"Feng","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Industrial Engineering University of Toronto  Toronto Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7347-8488","authenticated-orcid":false,"given":"Zhi\u2010bo","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Supramolecular Structure and Materials, College of Chemistry Jilin University  Changchun P.
