Biography:

Dr. Jianguo Guan, Changjiang Scholar Distinguished Professor of MOE, Chief Professor of Wuhan University of Technology (WUT), China. He is also Dean Education for the International School of Materials Science and Engineering, WUT. He received BS degree from Xi’an Jiaotong University in 1990, and gained his PhD degree (Electronic Materials and Devices) in 1995 from Huazhong University of Science and Technology, China. Afterwards, he joined State Key Laboratory of Advanced Technology for Materials Synthesis and Processing (SKLARMSP), WUT and became a full professor in 1998. Since then he has been leading the Division of Nanocomposite technology and Functional Composite Materials in SKLARMSP. From 2000 to 2001, he worked as a Research Fellow in Nanyang Technological University, Singapore. From 2008 to 2009, he worked as a senior visiting scholar in Washington University in St Louis, USA. He has taken charge of over 30 projects including 4 projects of 863 hi-tech programs and 6 JPPT projects for national key equipment. He has co-authored more than 210 papers in SCI-indxed peer-reviewed journals including Chem Soc Rev, Adv Mater, Angew Chem Int Ed, Nano Lett, Adv Funct Mater, ACS Nano etc., as well as 34 authorized patents. He has been awarded several recognized Science and Technology Awards from Chinese government because of his academic achievements. 

His current research interests include conducting composite materials, electromagnetic metamaterials, micro-/nanomotors, and photonic crystals.



报告摘要:

自驱动微纳米马达能够自主运动, 在药物运输、生物传感、细胞分离、微手术和环境治理等方面有着重要的变革性应用前景。本报告在简要自驱动微纳米马达的基本概念、驱动机理、构建策略和研究现状的基础上,重点介绍我们首次提出的生物相容性镁基微马达和在生物和环境介质中具有本征趋化运动行为的功能化精子微马达。然后,演示包括双面神粒子,单层管状和各向同性粒子等各种结构的光控微纳米马达及其独特的运动控制性能,表明它们具备作为灵活的平台,以高度复杂的方式操纵和组装微型/纳米货物。最后,也将展望应用于生物体中的微纳米马达应该具有强大的推力、特异性感知能力、外部跟踪能力和在血管等生理环境中的自我定位能力。


Abstract: 

Micro-/nanomotors (MNMs) can perform autonomous motions, and has potential revolutionary applications in biomedicines, micro-/nanofabrication and environmental detection and remediation. After briefly introducing the basic concept, propulsion mechanisms, construction strategy and research status of micro-/nanomotors, this presentation will focus on biocompatible Mg-based micromotors firstly developed in our research group and free swimming functionalized sperm micromotors with intrinsic chemotactic motile behavior in biological and environmental media. Then, I will demonstrate light-controlled MNMs of various structures including Janus, single-layered tubular and isotropic structures. These intriguing properties offer them ample opportunities to act as motile platform to manipulate and assemble micro/nanocargoes in highly sophisticated ways. In the end, I will also present the prospects about MNMs operating in living bodies, which should have powerful thrusts, specific sensing, external tracking and self-targeting in physiological environment like blood vessels.
