We report nonlinear chiral photochemistry, where femtosecond infrared pulses are frequency\u2010doubled to both drive and track a transformation of chiral CdTe\/CdO nanohelices into CdO nanospheroids. Circularly polarized light induces a controlled oxidation sequence monitored in real time through second\u2010harmonic scattering intensity and chiroptical contrast. As the CdO shell fractures and exposes non\u2010centrosymmetric CdTe, second\u2010harmonic intensity rises twenty\u2010fold, polarization reverses, and characteristic CdTe photoluminescence emerges. These findings are enabled by the experimental observation of the second\u2010harmonic hyper\u2010Mie optical activity effect, which completes a suite of nonlinear chiroptical scattering phenomena predicted over 45 years ago. Our results offer a spatially confined, selective, and temporally\u2010resolved method for material transformation.<\/jats:p>","DOI":"10.1002\/adma.73593","type":"journal-article","created":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T08:13:22Z","timestamp":1781165602000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Second\u2010Harmonic Hyper\u2010Mie Optical Activity Enables Closed\u2010Loop Chiral Photochemistry"],"prefix":"10.1002","volume":"38","author":[{"given":"Hoyeon","family":"Choi","sequence":"first","affiliation":[{"name":"Centre For Photonics Department of Physics University of Bath  Bath UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kody","family":"Whisnant","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering University of Michigan  Ann Arbor Michigan USA"},{"name":"Biointerfaces Institute University of Michigan  Ann Arbor Michigan USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ben J.","family":"Olohan","sequence":"additional","affiliation":[{"name":"Centre For Photonics Department of Physics University of Bath  Bath UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1034-3843","authenticated-orcid":false,"given":"E.","family":"Petronijevic","sequence":"additional","affiliation":[{"name":"SBAI Department La Sapienza University of Rome  Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2200-550X","authenticated-orcid":false,"given":"G.
