Fluorescent probes (fluoroprobes) such as thioflavin T have been essential tools for studying tau aggregation; however, most of them do not discriminate between amyloid fibril conformations (polymorphs). This gap is due, in part, to a lack of high-throughput methods for screening large, diverse chemical collections. Here we leverage advances in protein-adaptive differential scanning fluorimetry to screen the Aurora collection of 300+ fluoroprobes against multiple synthetic fibril polymorphs, including those formed from tau, \u03b1-synuclein and islet amyloid polypeptide. This screen\u2014coupled with excitation-multiplexed bright-emission recording (EMBER) imaging and orthogonal secondary assays\u2014revealed pan-fibril-binding chemotypes, as well as fluoroprobes selective for fibril subsets. One fluoroprobe recognized tau pathology in ex vivo brain slices from Alzheimer\u2019s disease and rodent models. We propose that these scaffolds represent entry points for developing fibril-selective ligands.<\/jats:p>","DOI":"10.1038\/s41557-025-01889-7","type":"journal-article","created":{"date-parts":[[2025,8,14]],"date-time":"2025-08-14T09:02:42Z","timestamp":1755162162000},"page":"1565-1575","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["High-throughput discovery of fluoroprobes that recognize amyloid fibril polymorphs"],"prefix":"10.1038","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6766-4245","authenticated-orcid":false,"given":"Emma C.","family":"Carroll","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2524-2201","authenticated-orcid":false,"given":"Hyunjun","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1281-4605","authenticated-orcid":false,"given":"Wyatt C.","family":"Powell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1164-4816","authenticated-orcid":false,"given":"Annemarie F.","family":"Charvat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abby","family":"Oehler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia G.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly M.","family":"Montgomery","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Yung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zoe","family":"Millbern","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3131-3619","authenticated-orcid":false,"given":"Alexander I.
