| 英文摘要 | Here we present a very simple and fast method for preparation of carbon quantum dot/silver (CQD/Ag) nanocomposites at room temperature. Glucose-derived CQDs were prepared by a facile microwave-assisted method and used as both reducing and stabilizing agents for synthesis of CQD/Ag nanocomposites. We found that a unique interaction between as-prepared nanocomposites and anti thyroid drug methimazole occurs in the solution, which results in a sharp color change from yellow to red. At the same time, the intensity of surface plasmon resonance peak of CQD/Ag nanocomposites at 400 nm decreases and a new peak appears at higher wavelengths. This finding formed a basis for developing a new colorimetric detection method for methimazole. The calibration curve for this drug was linear in the concentration range of 2.0-40 mu gL(-1) with a detection limit of 1.0 mu g L-1. The method was applied to the determination of methimazole in urine samples with satisfactory results. (C) 2017 Elsevier B.V. All rights reserved. |
