摘要：
Fluorescent molecularly imprinted polymers (MIPs) have attracted increasing attentions in recent years due to their high selectivity and sensitivity for target molecules. In this study, two cholic acid imprinted fluorescent polymers, i.e., MIP<inf>1</inf>and MIP<inf>2</inf>, were prepared using 4-dimethylamino-N-allylnaphthalimide (F<inf>1</inf>) and 4-piperazinyl-N-allylnaphthalimide (F<inf>2</inf>) as the fluorescent functional monomers, respectively. The fluorescence intensity of MIP<inf>1</inf>decreased linearly with the increase of the template concentration in the range of 1.50-120.0 μM, while the fluorescence intensity of MIP<inf>2</inf>increased linearly with the increase of the template concentration in the range of 0.40-110.0 μM. The detection limits of MIP<inf>1</inf>and MIP<inf>2</inf>for cholic acid were 0.42 and 0.083 μM, respectively. The mechanisms of the fluorescence responsive of the imprinted polymers were discussed. The results of fluorescence measurement and binding experiments demonstrated that both imprinted polymers have high recognition abilities and binding affinities for the template. The imprinted polymers have been successfully applied to the determination of cholic acid in human serums. The present study indicated that 1,8-naphthalimide can be used as a modular building block for design and construction of various fluorogenic molecularly imprinted materials for practical sensing and separation. ©2015 Elsevier B.V.

摘要：
This paper reports a new strategy for preparation of 2D molecularly imprinted materials (MIM) through the exploitation of thiol-ene click chemistry. 2D MIM for cholesterol was prepared using cholesterol as the template, acrolyl-modified β-cyclodextrin (acrolyl-β-CD) as the functional monomer, and thiol-modified SBA-15 (thiol-SBA-15) as the supporter. In this method, acrolyl-β-CD molecules were assembled around the templates by formation of template–monomer inclusion compounds. Then the acrolyl-β-CD molecules were anchored to the walls of the mesopores of SBA-15 via the thiol-ene click chemistry. After removal of the template molecules, the resulting recognition sites were formed in the mesopores of SBA-15. TEM, XRD, and N<inf>2</inf>adsorption–desorption analysis results demonstrated that the synthesized MIM had a highly ordered mesoporous structure. Results from FT-IR revealed that acrolyl-β-CDs have been successfully conjugated to SBA-15. The density of β-CDs attached on the MIM is determined by EA and TGA. The equilibrium binding amounts of MIM and non-imprinted materials (NIM) for cholesterol are 53.50 and 25.24 μmol/g, respectively. The 2D MIM exhibited binding affinity and specificity for a group of analytes which have similar size and shape to those of template. The application of the prepared materials as stationary phases in thin layer chromatography was investigated preliminarily. The imprinted materials had higher retention ability for the template than the NIM. The retention factors (R<inf>f</inf>) of cholesterol on MIM and NIM are 0.62 and 0.81, respectively. The solid phase extraction of cholesterol using MIM as the adsorbent was further investigated. The recoveries of the molecularly imprinted solid phase extraction column for cholesterol were 77.1–94.7 % with relative standard deviations (RSD) of 2.25–6.78 %. ©2016, Springer Science+Business Media New York.

摘要：
The graphene-polyvinylpyrrolidone composite film modified acetylene black paste electrode (GR-PVP/ABPE) was fabricated and used to determine vanillin. In 0.1 M H3PO4 solution, the oxidation peak current of vanillin increased significantly at GR-PVP/ABPE compared with bare ABPE, PVP/ABPE and GR/ABPE. The oxidation mechanism was discussed. The experimental conditions that exert influence on the voltammetric determination of vanillin, such as supporting electrolytes, pH values, accumulation potential and accumulation time, were optimized. Besides, the interference, repeatability, reproducibility and stability measurements were also evaluated. Under the optimal experimental conditions, the oxidation peak current was proportional to vanillin concentration in the range of 0.02-2.0 μM, 2.0-40 μM and 40-100 μM. The detection limit was 10 nM. This sensor was used successfully for vanillin determination in various food samples. ©2015 Elsevier Ltd. All rights reserved.

结题摘要：
本课题主要利用具有生物相容性的壳聚糖和优异性能的纳米材料制备新型电化学传感器，最终构建环境内分泌干扰物等重要小分子的高灵敏和高选择检测方法。本项目取得的主要成果有：1、以双酚A为模板分子，壳聚糖为功能单体和成膜材料，乙炔黑为理想导电材料，通过滴涂法结合硫酸交联在乙炔黑糊电极表面制备了分子印迹壳聚糖膜。该印迹电极对双酚A呈现了高灵敏和高选择的电化学响应。2、将氧化石墨烯与壳聚糖、双酚A按一定比例超声混合，将其修饰于乙炔黑糊电极表面，交联后用电化学诱导洗脱模板分子双酚A，再采用恒电位还原技术将氧化石墨烯还原，制得掺杂石墨烯的分子印迹壳聚糖膜修饰电极，该电极成功用于食品中残留双酚A的检测。3、采用绿色天然的壳聚糖作为分散剂和还原剂，在90℃水浴加热的条件下还原氧化石墨烯，制得壳聚糖-石墨烯分散液，将该分散液修饰在乙炔黑糊电极的表面，可实现硝基苯酚异构体的同时检测。4、利用水杨醛对壳聚糖进行化学改性，用红外光谱对产物进行表征，并将此壳聚糖衍生物应用于修饰电极的制备，修饰剂与目标分子可通过氢键、静电力、π-π共轭等多种方式结合，同时乙炔黑的引入加速了电子传递速率。通过水杨醛改性壳聚糖和乙炔黑的协同作用，实现了一些酚类内分泌干扰物如双酚A、对硝基苯酚和一些生物小分子如色氨酸的灵敏检测，且电极的重现性和稳定性好。5、采用恒电位还原技术直接在乙炔黑糊电极表面制备石墨烯修饰电极，该修饰电极同时结合了石墨烯和乙炔黑两种纳米材料的优点，具有大的比表面积和优异电子传递能力，实现了双酚A的灵敏检测。此外，实验发现酪氨酸和色氨酸在该修饰电极上氧化峰电位差为115 mV，实现了色氨酸在高浓度酪氨酸存在下的高灵敏和高选择检测。6、让多个叠氮基修饰β-环糊精分子(azide-β-CD)组装在模板分子周围，得到超分子组装体。然后让超分子组装体进入炔基修饰的介孔氧化硅的纳米孔道内，通过点击反应将azide-β-CD链接在介孔氧化硅的纳米孔道内壁。除去模板分子，得到2D分子印迹材料。此外，我们利用“点击化学”反应，制备了具有双重识别能力的分子印迹复合微球。制备的新型印迹材料有望用于电化学传感器的制备。相关研究成果发表SCI论文18篇，项目主持人获第九届湖南省青年科技奖。

摘要：
Boronic acids are important for effective separation of biological active cis-diols. For the purpose of constructing a new type of saccharide-sensitive material which can not only provide convenient separation but also improve the access of boronic acid to guest molecules, the fluorogenic boronic acid terminated, thermo-sensitive polymers (BA-polyNIPAm) were grafted to an alkyne modified silica gel through the exploitation of click chemistry. The BA-polyNIPAm grafted silica gel (BA-polyNIPAm-SG) was characterized by FT-IR, fluorescence spectra, fluorescence microscopy, elemental analysis (EA), thermal gravimetric analysis (TGA), scanning electron microscope (SEM) and so on. BA-polyNIPAm-SG displayed affinity binding ability for saccharides under physiological pH value and allowed saccharides to be conveniently separated from solution. The maximum binding capacities for fructose and glucose are 83.2 mu mol/g and 70.4 mu mol/g polymer, respectively. The intensity of fluorescence emission of BA-polyNIPAm-SG increased with the increasing of fructose concentration. The present study provides a new kind of composite material which contains moveable and flexible grippers for recognizing and binding guest molecules. (C) 2014 Elsevier B.V. All rights reserved.

摘要：
A reliable sensor was fabricated by modifying an acetylene black paste electrode with graphene (denoted as GR/ABPE) for sensitive and selective determination of tryptophan (Trp). Due to the high sorption ability, large surface area and numerous active sites, the GR/ABPE showed a strong enhancement effect on the oxidation of Trp, and greatly increased the peak current. The parameters affecting the Trp determination were investigated. In 1.0 M H <inf>2</inf>SO<inf>4</inf> the voltammetric responses of Trp and tyrosine (Tyr) were well separated into two distinct peaks with peak potential difference (ΔE<inf>pa</inf>) of 115 mV. Under the optimized conditions, in the presence of 0.1 mM Tyr, the oxidation peak current of Trp was proportional to its concentration in the range between 0.1 μM and 0.1 mM, with the limit of detection of 60 nM (S/N = 3). The GR/ABPE was applied to the direct detection of Trp in pharmaceutical and biological samples with satisfactory results. This work provides a simple and easy approach to selective detection of Trp in the presence of Tyr. ©2013 Elsevier B.V.

摘要：
The two-dimensional (2D) molecular imprinting approach has attracted extensive research interest in recent years due to its potential advantages such as simple construction, fast template removal and rapid mass transfer. In this study, a new 2D imprinting approach based on the combination of mesoporous silica materials and molecular imprinting technology is reported. 2D molecularly imprinted materials (MIMs) for cholesterol were prepared by using cholesterol as the template, azide modified β-cyclodextrin (azide-β-CD) as the functional monomer and alkynyl-modified SBA-15 (alkyne-SBA-15) as the skeleton. In this method, azide-β-CD molecules were first assembled around the templates by formation of template-monomer complexes, and thus the mutual positions of azide-β-CD molecules were fixed. Then, azide-β-CD molecules were anchored to the walls of the nano-pores of SBA-15 via click chemistry. After removal of the template molecules, the resulting cavities, i.e., recognition sites were formed in the nano-pores of mesoporous silicas. The synthesized MIM was characterized by FT-IR, X-ray diffraction (XRD), elemental analysis (EA), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM) and so on. Binding kinetic experiments demonstrated that the 2D imprinting approach can improve site accessibility for the template effectively. The 2D MIM exhibited binding affinity and specificity for the template, as revealed by equilibrium binding experiments. When using MIM as a stationary phase for HPLC, baseline separation of cholesterol from other compounds can be achieved. In addition, the use of 2D imprinting significantly reduced the peak broadening and tailing. This journal is ©The Royal Society of Chemistry.

摘要：
We describe a simple and sensitive voltammetric method for the simultaneous determination of 2-nitrophenol and 4-nitrophenol. It is based on the use of an acetylene black paste electrode modified with a graphene-chitosan composite film (denoted as Gr-Chit/ABPE). The reduction peak currents of 2-nitrophenol (at -252 mV) and of 4-nitrophenol (at -340 mV) in pH 1.0 solution increase significantly at the Gr-Chit/ABPE in comparison to a bare ABPE. Factors affecting sensitivity were optimized and a linear relationship is found between peak current and the concentrations of 2-nitrophenol (in the 0.4 μM to 80 μM range) and for 4-nitrophenol (in the 0.1 μM to 80 μM range). The detection limits (at an SNR of 3 and after a 30-s accumulation time) are 200 nM for 2-nitrophenol and 80 nM for 4-nitrophenol, respectively. The modified electrode was successfully applied to the direct and parallel determination of 2-nitrophenol and 4-nitrophenol in spiked water samples.
