理学院举办高妍博士学术讲座：环境与生物介质中纳米颗粒研究
- 2025年6月13日消息
汕头大学理学院于2025年6月13日14:30在高水平实验楼C302举办了一场学术讲座，主题为“环境与生物介质中纳米颗粒的分离测定与迁移过程”。本次讲座是理学院“科学沙龙”系列、广东省海洋生物技术重点实验室系列、省市共建海洋灾害预警与防护广东省重点实验室系列以及海洋科学长基计划建设系列讲座的一部分。
报告人高妍博士来自广州大学，她于山东大学获得博士学位，并在广州大学从事博士后研究，期间于2023-2024年在澳门大学进行交流博士后工作。高博士的研究专注于环境中纳米颗粒的分离测定与生物效应，以第一/共同第一/通讯作者身份在Water Research、Analytical Chemistry等国际期刊发表SCI论文8篇，合作发表10余篇，获得中国博士后科学基金、国家资助博士后研究人员计划C档资助及中国分析测试学会科学技术奖一等奖等荣誉。
讲座中，高博士系统介绍了纳米颗粒在环境与生物介质中的迁移转化过程和技术瓶颈，重点讲解了蛋白冠诱导萃取方法的开发与应用，该方法显著提升了复杂介质中纳米颗粒的富集效率并保持其原始形态。研究还揭示了纳米颗粒在水生生物中的粒径依赖性累积特征和毒理效应，为新污染物风险评估提供了理论和方法学基础。
该讲座吸引了全校师生参与，体现了汕头大学在环境科学领域的学术交流活力。
College of Science Hosts Academic Lecture by Dr. Gao Yan on Nanoplastics in Environmental and Biological Media
- June 13, 2025 News
The College of Science at Shantou University held an academic lecture at 14:30 on June 13, 2025, in High-Level Experimental Building C302, titled "Separation, Determination, and Migration Processes of Nanoparticles in Environmental and Biological Media." This event was part of the "Science Salon" series, the Guangdong Provincial Key Laboratory of Marine Biotechnology series, the Guangdong Provincial Key Laboratory of Marine Disaster Warning and Prevention series, and the Marine Science Long-Term Foundation Construction series.
The speaker, Dr. Gao Yan from Guangzhou University, earned her Ph.D. from Shandong University and conducted postdoctoral research at Guangzhou University, with a visiting postdoctoral position at the University of Macau from 2023 to 2024. Dr. Gao's research focuses on the separation, determination, and biological effects of nanoparticles in the environment. She has published 8 SCI papers as first/co-first/corresponding author in journals such as Water Research and Analytical Chemistry, co-authored over 10 additional papers, and received awards including grants from the China Postdoctoral Science Foundation and the CAIA Award.
During the lecture, Dr. Gao addressed challenges in detecting nanoparticles and presented a protein corona-induced extraction method that enhances enrichment efficiency while preserving particle morphology. Her work also explores the size-dependent accumulation and toxicological effects of nanoparticles in aquatic organisms, laying a foundation for risk assessment of emerging pollutants.
The lecture welcomed participation from the university community, showcasing Shantou University's dedication to scientific discourse and innovation.
