The molecule imprinted quantum dots (MIP@QDs) were constructed by coating molecular imprinted polymers layer on the surface of ZnS: Mn2+ QDs using the surface molecular imprinting technology. The developed MIP@QDs-based sensor was used for rapid and selective fluorescence sensing of sulfanilamide in water samples. The binding experiments showed that the MIP@QDs has rapid fluorescent responses, which are highly selective of and sensitive to the detection of sulfanilamide. The respond time of the MIP@QDs was 5 min, and the imprinting factor was 14.8. Under optimal conditions, the developed MIP@QDs-based sensor shows a good linearity (R2 = 0.9916) over a sulfanilamide concentration range from 2.90 \u00d7 10\u22128 to 2.90 \u00d7 10\u22126 mol L\u22121, with a detection limit of 3.23 \u00d7 10\u22129 mol L\u22121. Furthermore, the proposed MIP@QDs-based sensor was applied to the determination of sulfanilamide in real samples, with recoveries of 96.80%\u2013104.33%, exhibiting good recyclability and stability. Experimental results showed that the prepared MIP@QDs has the potential to serve as a selective and sensitive sensor for the fluorescence sensing of sulfonamides in water samples.<\/jats:p>","DOI":"10.3390\/polym14173540","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T22:53:42Z","timestamp":1661813622000},"page":"3540","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Molecular Imprinted ZnS Quantum Dots-Based Sensor for Selective Sulfanilamide Detection"],"prefix":"10.3390","volume":"14","author":[{"given":"Xin","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Life Science and Agricultural Engineering, Nanyang Normal University, Nanyang 473061, China"},{"name":"Research Center of Henan Provincial Agricultural Biomass Resource Engineering and Technology, Nanyang 473061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengfei","family":"Jiao","sequence":"additional","affiliation":[{"name":"School of Life Science and Agricultural Engineering, Nanyang Normal University, Nanyang 473061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yihan","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Life Science and Agricultural Engineering, Nanyang Normal University, Nanyang 473061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuping","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Life Science and Agricultural Engineering, Nanyang Normal University, Nanyang 473061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"362","DOI":"10.1080\/02652030500499359","article-title":"Analysis of sulphonamide residues in edible animal products: A review","volume":"23","author":"Wang","year":"2006","journal-title":"Food Addit.
