Abstract

After optimization of fabrication conditions, the capacitively coupled plasma-treated polyimide (PI) substrates were coated with composites of molecularly imprinted polymers and CdTe quantum dots and used to detect tetracycline (Tc) in the range of 5–3000 μM (R² = 0.9995) with a LOD of 0.2 μM (S/N = 3, RSD = 2.2% at 5 μM Tc, n = 10) by using a fluorescent quenching effect. The selectivity of the stripped PIs was evaluated by the imprinting factors (IFs) for Tc (IF = 7.2), other Tc analogues (IF = 3.4–5.3), and steroids (IF ≈ 1) and by the recoveries of 5 μM Tc from bovine serum albumin at 300 μg/mL (98%, RSD = 3.2%, n = 5), fetal bovine serum at 1.5 ppt (98%, RSD = 2.8%, n = 5), and liquid milk (94.5%, RSD = 5.3%, n = 5).

摘要

在优化制造条件之后，电容耦合的等离子处理的聚酰亚胺（PI）基板上涂有分子印迹聚合物和CdTe量子点的复合物，并用于检测5–3000μM（R ² = 0.9995 ）范围内的四环素（Tc）。），通过荧光猝灭效应使LOD为0.2μM（S / N = 3，在5μMTc时RSD = 2.2％，n = 10）。通过Tc（IF = 7.2），其他Tc类似物（IF = 3.4–5.3）和类固醇（IF≈1）的印迹因子（IFs）以及通过从中提取5μMTc的回收率评估剥离的PI的选择性牛血清白蛋白300μg/ mL（98％，RSD = 3.2％，n= 5），1.5 ppt的胎牛血清（98％，RSD = 2.8％，n = 5）和液态奶（94.5％，RSD = 5.3％，n = 5）。
