中文摘要:有机纳米材料是指基于脂质、蛋白、多糖及有机高分子聚合物的新型纳米材料。近年来,随着纳米科技的发展,有机纳米材料已被广泛应用于食品、农业、生物医药等行业中。虽然有机纳米材料独特的性质使其具有很大的应用潜力,但同时也存在潜在的健康风险。一些难降解的有机纳米粒子能够通过人类活动被排入环境中,并在生物体中不断累积。因此,有机纳米材料的安全性研究日益受到重视,对其分析表征方法也提出了新的要求。目前对有机纳米材料的分析主要包括样品处理、分离、表征、检测等步骤,其中主要涉及过滤、离心、电镜、色谱、光谱、质谱等技术。该文综述了目前有机纳米材料的应用及其分析方法的研究进展,并对未来研究趋势进行了展望。

Progresses in Application and Analytical Methods of Organic Nanomaterials
Abstract:Organic nanomaterials(ONMs)generally refer to nanomaterials based on lipids,proteins,polysaccharides and polymers.In recent years,ONMs have been widely used in food,agriculture,and biomedical industries with the rapid development of nanotechnology.Although the unique properties of ONMs endow them great application potentials,they still have some potential toxicity to organisms.Some ONMs are difficult to degrade,and they might be discharged into the environment through human activities,and accumulated in the organisms.Therefore,the safety assessment on ONMs has attracted increasing research interest.This also raises new challenges toward their characterization and analytical methods.The analysis of ONMs often includes procedures of sample preparation,separation,characterization and detection.Many techniques are involved such as filtration,centrifugation,chromatography,electron microscopy,spectroscopy and mass spectrometry.The current progresses in the application and development of analytical methods of ONMs are summeried in this article.The perspectives on the future research in this area are also proposed.
