| 英文摘要 | A novel molecular imprinting fluorescence nanosensor was constructed via a facile surface imprinting polymerization one-pot synthesis strategy for highly selective and sensitive recognition and detection of 4-nitrophenol (4-NP) based on an electron-transfer induced fluorescence quenching mechanism. 2-Aminoethyl methacrylate hydrochloride (AMA) was first used as a surfactant to interact with aqueous carboxyl-CdTe quantum dots (QDs) and the resultant AMA-modified QDs were used as a core support and a fluorescent signal source. Then, an ultrathin 4-NP imprinted shell (ca. 4 nm) was formed on the QD surface (i.e., QD@MIPs) by a simple facile free radical polymerization step. The one-pot synthesis simplified the imprinting process and shortened the experimental period. The imprinted sites bound the template of 4-NP efficiently through the hydrogen bonding interactions and showed excellent recognition selectivity for 4-NP over its analogues with a high imprinting factor of 9.1. The electron transfer process between QDs and 4-NP led to significant fluorescence quenching of the QD@MIPs nanosensor, by which 4-NP could be sensed, and high detection sensitivity up to 0.051 mu M was attained. Furthermore, the sensor was successfully applied to determine 4-NP in seawater and lake water samples, presenting high recoveries in the range of 92.7-109.2% at three spiking levels with the relative standard deviation within 3.1-4.8%. The simple, rapid, reliable QD@MIPs-based method proved to be potentially applicable for the highly selective and sensitive fluorescence determination of trace 4-NP in complicated environmental water samples. |
