Infected animals, such as swine, develop vesicles, often leading to morbidity or depopulation of exposed herds. Current FMD diagnosis relies on serologic and immuno-based methods, which commonly encounter cross-reactivity and cost issues. Therefore, a simple and portable diagnostic tool would greatly aid its detection efforts. This study generated a novel aptamer sequence targeting viral protein 1 (VP1) of serotype O FMD virus (FMDV) by Systematic Evolution of Ligands by Exponential Enrichment (SELEX). The generated FMDV VP1-specific aptamer sequence was characterized and incorporated into an Aptamer-linked Immobilized Sorbent Assay (ALISA)-based microplate platform to detect FMDV VP1. Results showed that the aptamer, FMDV Apt, had an estimated dissociation constant (\n                    <jats:italic>K<\/jats:italic>\n                    <jats:sub>d<\/jats:sub>\n                    ) of 14\u2009\u00b1\u20098.6 nM, showing strong affinity for VP1 of FMDV. A concentration-dependent linear relationship (R\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u20090.9354) within a concentration range of 0.50 ng\/mL \u2013 5.0 ng\/mL of FMDV VP1 protein was observed. The limit of detection (LOD) was determined to be 1.3 ng\/mL, and the limit of quantification (LOQ) was approximately 4 ng\/mL. Moreover, the FMD ALISA did not exhibit cross-reactivity when tested with high concentrations (500 ng\/mL \u2013 2,000 ng\/mL) of non-targets, indicating its robustness and potential application in other detection platforms. The newly developed screening tool would facilitate efficient and inexpensive monitoring of potential biohazard risks posed by FMDV.\n                  <\/jats:p>","DOI":"10.1038\/s41598-025-34793-8","type":"journal-article","created":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T11:05:49Z","timestamp":1770116749000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Aptamer-linked immobilized sorbent assay for detection of VP1 of foot and mouth disease virus serotype O"],"prefix":"10.1038","volume":"16","author":[{"given":"Irwin A.","family":"Quintela","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymondo","family":"Lopez-Maga\u00f1a","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anya","family":"Hwang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tyler","family":"Vasse","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivian C.H.","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,2,3]]},"reference":[{"key":"34793_CR1","doi-asserted-by":"publisher","first-page":"104","DOI":"10.1126\/science.abd2475","volume":"374","author":"A Jolles","year":"2021","unstructured":"Jolles, A. et al.
