Prussian blue modified metal-organic framework MIL-101(Fe) with intrinsic peroxidase-like catalytic activity as a colorimetric biosensing platform 作者:Cui, FJ (Cui, Fengjuan)[ 1 ] ; Deng, QF (Deng, Qingfang)[ 1 ] ; Sun, L (Sun, Li)[ 1 ] RSC ADVANCES 卷: 5 期: 119 頁: 98215-98221 DOI: 10.1039/c5ra18589k 出版年: 2015 查看期刊信息 摘要 In this paper, a nanosized porous PB/MIL-101(Fe), was facilely prepared with a uniform octahedral structure by growing Prussian blue (PB) on the microporous metal-organic framework MIL-101(Fe), and confirmed by cyclic voltammogram (CV), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. It was demonstrated to possess intrinsic peroxidase-like activity and could catalytically oxidize 3,3',5,5'-tetramethylbenzidine (TMB), o-phenylenediamine (OPD), and 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (AzBTS) by H2O2 in solution to produce a typical colour change. As a novel peroxidase mimic material, PB/MIL-101(Fe) shows high catalytic efficiency. Kinetic analysis of as the as-prepared PB/MIL-101(Fe) was studied, and it gave a linear absorbance response from 2.40 mu M to 100 mu M with a limit of detection (LOD) of 0.15 mu M. It indicated that the catalytic behavior was consistent with typical Michaelis-Menten kinetics and follows a ping-pong mechanism. Interestingly, the K-m values for PB/MIL-101( Fe) with respect to TMB and H2O2 is 0.127 and 0.0580 mM were lower than those of MIL-101(Fe) (0.490 and 0.620 mM for TMB and H2O2), respectively. This is probably attributed to more active sites and the pores of the PB/MIL-101(Fe) for peroxidase substrates. More importantly, it can be easily functionalized with different compounds including silica coating (TEOS), 3-aminopropyltriethoxysilane (APTES), polyethylene glycol (PEG) or folic acid (FA) to make it biocompatible. The results reveal that the stability, ease of production and versatility of PB/MIL-101(Fe) nanoparticles could result in them being used as a promising tool for cancer cell detection. With these findings, a simple and sensitive colorimetric biosensing platform has been established. 關(guān)鍵詞 KeyWords Plus:HORSERADISH-PEROXIDASE; CARBON NANOTUBES; NANOPARTICLES; GLUCOSE; ENZYME; FUNCTIONALIZATION; LUMINESCENCE; PERFORMANCE; MIL-53(FE); CHEMISTRY 作者信息 通訊作者地址: Cui, FJ (通訊作者) [顯示增強(qiáng)組織信息的名稱] Qiqihar Univ, Coll Chem & Chem Engn, Qiqihar 161006, Peoples R China. 地址: [顯示增強(qiáng)組織信息的名稱] [ 1 ] Qiqihar Univ, Coll Chem & Chem Engn, Qiqihar 161006, Peoples R China 電子郵件地址:cxf234@126.com 基金資助致謝 基金資助機(jī)構(gòu) 授權(quán)號 National Basic Research Program of China 2011CB935700 Postdoctoral Scientific Research Developmental Fund LBH-Q14158 Program for Yong Teachers Scientific Research in Qiqihar University 2014k-Z07 查看基金資助信息 出版商 ROYAL SOC CHEMISTRY, THOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLAND 類別 / 分類 研究方向:Chemistry Web of Science 類別:Chemistry, Multidisciplinary 文獻(xiàn)信息 文獻(xiàn)類型:Article 語種:English 入藏號: WOS:000365403000040 ISSN: 2046-2069 期刊信息 目錄： Current Contents Connect® Impact Factor (影響因子): Journal Citation Reports® 其他信息 IDS 號: CX0QZ Web of Science 核心合集中的 "引用的參考文獻(xiàn)": 51 Web of Science 核心合集中的 "被引頻次": 0 |
