However, the diagnostic methods for brucellosis have some disadvantages, such as low sensitivity, long detection time, professional operation, and high cost. This study aims to establish a convenient, fast, effective, and inexpensive detection method for brucellosis. Gold nanoparticles with \u03b2-cyclodextrin as a reducing agent were prepared and optimized, applied to rapid vertical flow technology (RVFT), and used to establish a kit for the detection of brucellosis. In this study, gold nanoparticles prepared from \u03b2-cyclodextrin were applied to RVFT for the first time, and on this basis, silver staining amplification technology was introduced, which further improved the sensitivity and reduced the detection limit of this method. Standard Brucella-Positive Serum (containing Brucella antibody at 4000 IU\/mL) could be detected in this system even for a dilution factor of 1 \u00d7 10\u22123. The detection limit was 4 IU\/mL. RVFT is simple to operate, has a short reaction time, and is 5\u20136 min visible to the naked eye, without any equipment.<\/jats:p>","DOI":"10.3390\/bios12070531","type":"journal-article","created":{"date-parts":[[2022,7,17]],"date-time":"2022-07-17T21:00:28Z","timestamp":1658091628000},"page":"531","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Gold Nanoparticles Prepared with Cyclodextrin Applied to Rapid Vertical Flow Technology for the Detection of Brucellosis"],"prefix":"10.3390","volume":"12","author":[{"given":"Ashe","family":"Fang","sequence":"first","affiliation":[{"name":"College of Life Sciences, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danni","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiushuang","family":"Luo","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"46","DOI":"10.1186\/s40249-021-00834-3","article-title":"Fluorescence polarization assay improves the rapid detection of human brucellosis in China","volume":"10","author":"Dong","year":"2021","journal-title":"Infect.
