{"doi":"10.1101/2025.09.30.25337017","title":"Surface Markers on Supermeres Outperform Extracellular Vesicles in Cancer Diagnosis","abstract":"Abstract Extracellular nanocarriers, such as extracellular vesicles (EVs), lipoproteins, supermeres, and exomeres are diverse lipid-protein-nucleic acid assemblies. Among them, supermeres hold significant diagnostic potential but are challenging to characterize due to limited surface biomarker information and labor-intensive isolation methods. This study introduces an isolation-free Ion Exchange Membrane Sensing method for detection of supermeres within 30 minutes using 50 μL of sample, with a sensitivity of 10 6 –10 7 supermeres/mL. Validation through ultracentrifugation and surface plasmon resonance confirms the detection accuracy and specificity. Supermeres carry key proteins such as HSPA13, ENO2, and DDR1 analogous to tetraspanin in EV. Supermeres outperform sEVs and exomeres across multiple shared and unique surface proteins critical to colorectal cancer diagnosis, highlighting their superior clinical utility and potential as next-generation biomarkers in precision medicine.","journal":"medRxiv","year":2025,"id":577113,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9533,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1486673,"name":"John Alex Sinclair","orcid":null,"position":1,"is_corresponding":false},{"id":1243418,"name":"Tiger Shi","orcid":"0009-0005-1699-2635","position":2,"is_corresponding":false},{"id":278293,"name":"Gaeun Kim","orcid":"0009-0008-1502-1847","position":3,"is_corresponding":false},{"id":991682,"name":"Runyao Zhu","orcid":"0009-0005-5109-0020","position":4,"is_corresponding":false},{"id":1486330,"name":"Grace Gasper","orcid":"0009-0008-4636-8739","position":5,"is_corresponding":false},{"id":436534,"name":"Yichun Wang","orcid":"0000-0002-4353-6660","position":6,"is_corresponding":false},{"id":327444,"name":"James N.
