讲座内容:

This talk will mainly introduce research work performed by Institute of Photonics and Advanced Sensing (IPAS), University of Adelaide. IPAS was built in 2005, and has been developing novel microstructured optical fibres and cavity devices for biochemical detection. The suspended core fiber is a micron or nano rod fixed within a glass tube. Due to small size , these fibers have strong evanescent field which can be used for molecular detection and its minimum detection limit can be down to nM level. Other sensing platforms developed in IPAS include surface plamon resonance fibre sensors and whispering gallery mode cavities. By using these sensing platforms, we have explored detection of a series of biochemicals, including diseases, environmental pollutants, monitoring of biochemical processes, food safety and adulterations.本报告将主要介绍阿德莱德大学光子和先进传感研究整个团体的工作。该研究所成立于2005 年,自主开发独特新颖的微结构光纤及微腔谐振器件,用于生物化学检测。悬芯光纤是一根固定在玻璃毛细管内的微米甚至纳米线, 由于芯径细小,利用其强烈的消逝场可以实现高灵敏度分子探测,最低探测极限可以低至纳摩尔。同时开发的新颖传感器平台还包括表面等离子体和回音壁共振仪。利用这些光纤平台,我们探索了一系列的生化检测技术,包括医学疾病探测,环境污染监控,生物化学工艺检测控制,食品安全及掺假检测等。


主讲人简介:

Dr Yinlan Ruan has been working in development of optical fibre communication devices and sensors since she obtained her Bachelor and Master degree from Huazhong University of Science and Technology, China. Dr Ruan worked in Wuhan Research Institute of Posts & Telecommunications between 1996-2001 for development and commercialization of optical fibre circulators. Dr Ruan studied in the Australian National University for PhD degree with her thesis as Chalcogneide waveguides for high capacity optical communications. She joined Institute of Photonics and Advanced Sensing, University of Adelaide in 2005 and has been working in development of microstructured and mid-infrared optical fibres and their applications in bio-chemical sensors for over 10 years. Compared to other types of chemical detection techniques, the advantages of the optical fibre sensors are to enable onsite high sensitivity detection and monitoring of biochemicals, resistant to the environment with high temperature and corrosion, and no interference from electromagnetic field. They are particularly suitable to be used in those areas hard to access. Dr Ruan is currently focusing on detection of toxic gases (pipeline leaking and oil exploration), environmental pollution monitoring and detection of food safety and adulteration with some seeking to be commercialized. Dr Ruan has published over 90 journal with citation of 1302. Her H-index is 17.阮博士于本科和硕士毕业于华中科技大学后一直从事光纤通讯器件及光纤传感器的研究开发工作。在1996-2001年间在武汉邮电科学院及武汉光迅公司从事无源通信器件的开发,并将光环行器产品商业化。2001-2005年间在澳大利亚国立大学攻读博士学位期间从事中红外硫化玻璃平面光波导高容量通讯器件的研发。2005年加入澳大利亚阿得莱德大学全球著名的光子和先进传感研究所后,从事特种微结构和红外光纤制造,以及光纤生物化学传感器开发工作达十余年。光纤传感检测系统相对于其它生化检测仪器的优点是可以实现化学分子的高灵敏度在线现场检测或监控,耐高温耐腐蚀,不受电磁波干扰,特别适合狭小空间。阮银兰博士现在的研究重点是将光纤传感器用于有毒气体检测(管道泄漏监控和石油勘探),环境污染探测以及食品安全和掺假监控, 并开始部分传感器的商业化应用。阮博士现发表学术期刊和会议论文90余篇,累计引用1302,H指数因子17。
