Detection test strip for dibutyl phthalate and preparation method thereof

The invention discloses a detection test strip for dibutyl phthalate. The test strip comprises a sample pad, a quantum dot labeling pad, a pyroxylin membrane, an absorption pad and a backboard, wherein the quantum dot labeling pad contains quantum dots-labeled dibutyl phthalate nano antibodies. The quantum dots based detection test strip for dibutyl phthalate disclosed by the invention combines a quantum dot technique with nano antibodies, and can carry out quick detection on dibutyl phthalate quantitatively with high sensitivity, strong specificity and less cross reaction, and the detection limit of dibutyl phthalate is as low as 1ng/ml. 本发明公开了种邻苯二甲酸二丁酯检测试纸条，所述试纸条包括样品垫、量子点标记垫、硝酸纤维素膜、吸水垫和背板；所述的量子点标记垫上含有量子点标记的邻苯二甲酸二丁酯纳米抗体；本发明中所述的基于量子点的邻苯二甲酸二丁酯检测试纸条通过将量子点技术和纳米抗体结合，可定量的对邻苯二甲酸二丁酯进行快速检测，灵敏度高，邻苯二甲酸二丁酯的检出限低至为1ng/ml；特异性强，交叉反应少。
