To address this issue, we explored the potential of combining the loop-mediated isothermal amplification (LAMP) technique with the affinity of aptamers to develop point-of-care testing. In this study, we utilized 60 serum samples. An aptamer capable of binding to the dengue virus was employed as a platform for capturing genetic material, and its performance was compared to a commercial kit. Dengue virus was detected through RT-PCR and colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP), allowing visual observation of the results without the need for equipment. In the context of the aptamer LAMP assay, our analysis revealed the detection of the dengue virus in 38 out of 60 samples, with 95% sensitivity and 100% specificity compared to RT-PCR and\/or APTA-RT-PCR. Importantly, we observed no cross-reaction when assessing samples positive for the zika virus, underscoring the assay\u2019s selectivity. This innovative aptameric capture of the viral RNA in combination with the RT-LAMP (APTA-RT-LAMP) method has the potential to offer valuable molecular insights into neglected infectious diseases in a simpler and faster manner.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>Dengue is a neglected tropical disease of significant epidemiological importance in tropical and subtropical countries. Current diagnostics for this infection present challenges, such as cross-reactivity in serological tests. Finding ways to enhance the diagnosis of this disease is crucial, given the absence of specific treatments. An accurate, simple, and effective diagnosis contributes to the improved management of infected individuals. In this context, our work combines molecular biology techniques, such as isothermal loop amplification, with aptamers to detect the dengue virus in biological samples. Our method produces colorimetric results based on a color change, with outcomes available in less than 2 hours. Moreover, it requires simpler equipment compared to molecular PCR tests.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1128\/spectrum.03583-23","type":"journal-article","created":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T13:05:23Z","timestamp":1721826323000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["Aptamer-associated colorimetric reverse transcription loop-mediated isothermal amplification assay for detection of dengue virus"],"prefix":"10.1128","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3402-2151","authenticated-orcid":true,"given":"Vit\u00f3ria de Oliveira","family":"Arruda","sequence":"first","affiliation":[{"name":"Institute of Physics, Universidade Federal de Catal\u00e3o, Catal\u00e3o, Goi\u00e1s, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luiz Ricardo Goulart","family":"Filho","sequence":"additional","affiliation":[{"name":"Institute of Biotechnology, Universidade Federal de Uberl\u00e2ndia, Uberl\u00e2ndia, Minas Gerais, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2299-2114","authenticated-orcid":false,"given":"Adriana Freitas","family":"Neves","sequence":"additional","affiliation":[{"name":"Institute of Biotechnology, Universidade Federal de Catal\u00e3o, Catal\u00e3o, Goi\u00e1s, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0006037"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature12060"},{"key":"e_1_3_3_4_2","volume-title":"Comprehensive guidelines for prevention and control of Dengue and Dengue Haemorrhagic fever","author":"World Health Organization","year":"2011","unstructured":"World Health Organization. 2011.
