To achieve rapid, sensitive and specific detection of AFB1, a label-free D-shaped optical fiber sensor based on lossy mode resonance (LMR) was developed in this study. The sensor was fabricated by depositing a SnO\n                    <jats:sub>2<\/jats:sub>\n                    thin film on the polished surface of a D-shaped optical fiber as the LMR sensitive layer and immobilizing anti-AFB1 antibodies on the SnO\n                    <jats:sub>2<\/jats:sub>\n                    surface to construct a specific biorecognition interface. The specific binding between AFB1 in the sample and the immobilized anti-AFB1 antibodies causes a change in the effective refractive index (RI) on the fiber surface, thereby causing variation in transmission spectrum. Experimental results show that the fabricated sensor exhibits a good response to AFB1 in the concentration range of 0.1\u2013100\u2005ng\/mL with excellent specificity. The sensor\u2019s limit of detection (LOD) was approximately 0.071\u2005ng\/mL. In addition, the proposed D-shaped optical fiber LMR sensor was successfully applied to the detection of AFB1 in real food samples such as peanuts, corn, wheat, and millet, which provided a promising approach for the rapid and sensitive detection of AFB1 in food and agricultural samples, with broad application prospects in food safety supervision.\n                  <\/jats:p>","DOI":"10.1364\/oe.591849","type":"journal-article","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T05:00:09Z","timestamp":1775710809000},"page":"15742","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["D-shaped optical fiber lossy mode resonance biosensor for label-free detection of aflatoxin B1"],"prefix":"10.1364","volume":"34","author":[{"given":"Li","family":"Deng","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2629-9173","authenticated-orcid":true,"given":"Jinze","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Sun","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengwei","family":"Ao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yizhe","family":"Tian","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Bai","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Qian","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05s92vm98","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Liu","sequence":"additional","affiliation":[{"name":"Shaanxi University of Chinese Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5781-410X","authenticated-orcid":true,"given":"Jiawei","family":"Xi","sequence":"additional","affiliation":[{"name":"Norinco Group Testing and Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,4,17]]},"reference":[{"key":"oe-34-8-15742-R1","doi-asserted-by":"publisher","first-page":"27513","DOI":"10.1038\/s41598-025-13249-z","type":"journal-article","volume":"15","author":"Feizy","year":"2025","journal-title":"Sci.
