摘要

本文以磁性四氧化三铁纳米粒子(Fe3O4)为纳米基底,苏丹红 III(SRIII)为模板分子,甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EGDMA)为交联剂,以 2,2′-偶氮二异丁腈(AIBN)为引发剂,制备了一种新型双功能磁性表面分子印迹聚合物纳米探针(Fe3O4)、以甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EGDMA)为交联剂,2,2′-偶氮二异丁腈(AIBN)为引发剂,采用微波辐照法制备了一种具有识别功能和富集功能的新型双功能磁性表面分子印迹聚合物纳米探针(Fe3O4@MIP)。通过分子光谱、电子显微镜、能谱和比表面积对该探针进行了表征。探针在 370 nm 处出现共振瑞利散射(RRS)峰,随着 SRIII 浓度的增加,RRS 能量转移(RRS-ET)效应增强,370 nm 处的 RRS 强度呈线性下降。该方法灵敏度高、选择性好,检出限为0.017 nmol/L。实际样品的回收率为93.1∼106 %,相对标准偏差(RSD)为3.14∼8.37 %。通过磁分离,SRIII 的 Fe3O4@MIP 探针富集率为 100。

A facile and selective resonance Rayleigh scattering method for trace Sudan Red III with magnetic nanosurface molecularly imprinted polymethacrylic acid probe
In this article, using magnetic iron tetraoxide nanoparticles (Fe3O4) as the nanosubstrate, Sudan red III (SRIII) as the template molecule, methacrylic acid (MAA) as the functional monomer, ethylene glycol di-methacrylate (EGDMA) as the cross-linking agent, and 2,2′-azobisisobutyronitrile (AIBN) as the initiator, a new bifunctional magnetic surface molecularly imprinted polymer nanoprobe (Fe3O4@MIP) with both recognition function and enrichment function was prepared by the microwave irradiation procedure. The probe was characterized by molecular spectra, electron microscopy, energy spectroscopy and specific surface areas. The probe exhibits a resonance Rayleigh scattering (RRS) peak at 370 nm, the RRS energy transfer (RRS-ET) effect was enhanced with the increase of SRIII concentration, and the RRS intensity at 370 nm was decreased linearly. Accordingly, a new RRS-ET method was developed for the sensitive and selective determination of 0.05–1 nmol/L SRIII, with a detection limit of 0.017 nmol/L. The recoveries were in the range of 93.1∼106 % with the relative standard deviations (RSDs) in the range of 3.14∼8.37 % for the real samples. The enrichment ratio of Fe3O4@MIP probefor SRIII was 100 by means of the magnetic separation.

期刊介绍: The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects. The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
