场流分离技术及其应用学术交流

分会介绍

       新污染物筛查、食品安全保障、精准诊疗技术发展等是当前我国科技创新的重要方向。在这些领域中，纳米至微米尺度的细颗粒广泛存在且影响深远，例如环境中的微纳塑料与天然胶体，食品中的蛋白质聚集体，以及生物体内的外泌体、病毒颗粒和纳米药物载体。对这些细颗粒的精准分离与表征，不仅关系到相关环境与健康风险的科学认知，也对分离科学提出了从原理到仪器的全新挑战。场流分离（FFF）凭借无固定相、温和无损、分辨率高、尺寸覆盖范围宽（理论涵盖 1 nm~100 μm）并能与多角度光散射、ICP-MS、高分辨质谱等多种检测器在线联用等独特优势，已成为细颗粒分析的“利器”，在生物医药、环境化学、食品科学及纳米毒理学等领域展现出富有前景的应用潜力。本分会旨在举办场流分离领域高水平学术交流研讨会，内容将聚焦但不限于：①场流分离基础理论与分离机理新见解；②新型场流分离仪器的研制；③场流分离-多检测器联用新方法；④场流分离在分析化学、环境化学、食品科学与生物医药等前沿领域中的应用。分会将设特邀报告、口头报告等多种交流形式，鼓励思想碰撞与跨学科交流。我们诚挚欢迎从事分离科学、分析化学、环境与健康、食品分析、纳米生物医药等领域的专家学者和青年学子踊跃投稿参会，分享最新成果，共话场流分离的现在与未来，让这项技术更好地服务于科学研究与应用的需求。

Session Theme

Academic communication on field-flow fractionation technology and its applications

Session Introduction

The screening of emerging contaminants, food safety assurance, and the development of precision diagnostic technologies are currently key priorities in China's scientific and technological innovation landscape. Fine particles ranging from nano- to micrometer scales are ubiquitous in these areas and have significant implications—for instance, micro- and nanoplastics and natural colloids in environmental samples, protein aggregates in food products, and exosomes, viral particles, and nanomedicine carriers in biological systems. Accurate separation and characterization of these fine particles are essential for understanding their environmental and health impacts, and also present new challenges to separation science in terms of both fundamental principles and instrumentation.

Field-flow fractionation (FFF) offers a unique combination of advantages: it requires no stationary phase, is gentle and non-destructive to samples, provides high resolution, covers a broad size range (theoretically from 1 nm to 100 μm), and can be readily coupled online with multiple detectors such as multi-angle light scattering, ICP-MS, and high-resolution mass spectrometry. These features have made FFF an indispensable tool for fine particle analysis, with growing applications in biomedicine, environmental chemistry, food science, and nanotoxicology.

This session is intended to serve as a high-level platform for academic exchange in the field of field-flow fractionation. Topics of interest include, but are not limited to: (1) fundamental theories of FFF and novel insights into separation mechanisms; (2) development of new FFF instrumentation; (3) new methodologies for FFF coupled with multi-detector systems; and (4) applications of FFF in emerging areas such as analytical chemistry, environmental chemistry, food science, and biomedicine. The session will feature invited talks and oral presentations, with the goal of fostering interdisciplinary discussion and the exchange of ideas. We warmly welcome researchers and students working in separation science, analytical chemistry, environmental and health sciences, food analysis, nanobiomedicine, and related fields to submit abstracts and join us at the symposium. We look forward to sharing recent advances and discussing the future of field-flow fractionation, so that this technology may better serve both scientific research and practical needs.
