This paper proposes a novel fluorescent molecularly imprinted polymer (MIP), SiO<jats:sub>2<\/jats:sub>@CdTe QDs@MIP, for PQ detection and adsorption. The MIP was synthesized using 3\u2010aminopropyltriethoxysilane as the functional monomer, 4,4\u2032\u2010bipyridyl as the template molecule, and tetraethoxysilane as the cross\u2010linker. In addition, CdTe quantum dots featuring unique optical characteristics and excellent photochemical stability were combined as signal reporter. The synthesized MIP had a Brunauer\u2013Emmett\u2013Teller surface area of 68.2 m<jats:sup>2<\/jats:sup>\/g, pore volume of 0.42 cm<jats:sup>3<\/jats:sup>\/g and pore size of 6.9 nm, demonstrating the potential for both PQ detection and adsorption. For PQ detection, the MIP could achieve three orders of magnitude better than the limit of detection, and one order of magnitude wider detection range than existing methods. The PQ recovery values for real samples of water and corn were 96.4\u2013102.1% and 93.9\u201397.3%, respectively. The amount of PQ detected by the MIP was within 98.05% on average of that using high\u2010performance liquid chromatography. For PQ adsorption, the MIP had an adsorption capacity of 3.36 mg\/g, and followed a pseudo\u2010second\u2010order kinetic model with excellent toxicological characteristics. Overall, the novel SiO<jats:sub>2<\/jats:sub>@CdTe QDs@MIP proposed in this paper could facilitate an efficient and convenient method for PQ detection and adsorption.<\/jats:p>","DOI":"10.1002\/bio.3949","type":"journal-article","created":{"date-parts":[[2020,9,18]],"date-time":"2020-09-18T01:32:42Z","timestamp":1600392762000},"page":"345-352","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["A novel fluorescent molecularly imprinted polymer SiO<sub>2<\/sub>@CdTe QDs@MIP for paraquat detection and adsorption"],"prefix":"10.1002","volume":"36","author":[{"given":"Jiadi","family":"Sun","sequence":"first","affiliation":[{"name":"State Key Laboratory of Food Science and Technology, School of Food Science and Technology, National Engineering Research Center for Functional Food, Synergetic Innovation Center of Food Safety and Quality Control Jiangnan University  Wuxi Jiangsu China"},{"name":"State Key Laboratory of Dairy Biotechnology, Shanghai Engineering Research Center of Dairy Biotechnology Dairy Research Institute, Bright Dairy &amp; Food Co., Ltd  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Food Science and Technology, School of Food Science and Technology, National Engineering Research Center for Functional Food, Synergetic Innovation Center of Food Safety and Quality Control Jiangnan University  Wuxi Jiangsu China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yinzhi","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Food Science and Technology, School of Food Science and Technology, National Engineering Research Center for Functional Food, Synergetic Innovation Center of Food Safety and Quality Control Jiangnan University  Wuxi Jiangsu China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3750-1007","authenticated-orcid":false,"given":"Xiulan","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Food Science and Technology, School of Food Science and Technology, National Engineering Research Center for Functional Food, Synergetic Innovation Center of Food Safety and Quality Control Jiangnan University  Wuxi Jiangsu China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,10,15]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cbi.2012.05.008"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/labinvest.2015.161"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2125.2011.04026.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/chromsci\/bmu041"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhazmat.2014.05.079"},{"key":"e_1_2_7_7_1","first-page":"961","volume":"74","author":"Chichila T.","year":"1991","journal-title":"J.
