College Introduction    

The IAS has been established at Shenzhen University to provide both undergraduate and
postgraduate education, focusing on interdisciplinary teaching and research. IAS will build
a team consisting of experienced professors with international vision and young teachers
with great potential. It will foster collaborations with world-class universities in Hong Kong
and abroad. By adopting best-practice management methods used by overseas research
universities, IAS aims to create an academic environment sensitive to progress made by
international peers, with the overall goal of attaining excellence in teaching, research and
management. IAS provides a special platform within Shenzhen University for exploring
innovative approaches to higher education and research.

Talk Information

自然条件下,细菌可独立浮游生存也可依附于表面,自组织、集体共生,由大量微生物群体粘附在表面共生行成的薄膜被称为生物被膜(biofilm),其厚度通常在 100-200µm之间。医学研究表明:生物膜感染会引起肺炎、尿道炎、肾结石、中耳炎、牙周炎等多种疾病,并因其对抗生素的抗性大幅增高,造成对这类感染的治疗极为困难。统计表明:生物膜感染和许多难以根治的反复性慢性感染,和约80%的急性院内致命感染有关。生物膜对植入性医疗机械(如人造器官,人工关节、骨骼支架等)或手术器具表面的污染会还会造成严重的术后感染,导致手术和移植的失败。在此,我将介绍如何通过发展一些新的原位表征方法去探索在铜绿假单胞菌生物被膜形成过程中涉及其形成机制的一系列核心问题,其中包括:1)细菌在表面初始粘附、运动过程;2)细菌表面的适应、菌落形成;及3)细菌群体的协作、通讯等过程等。我们研究表明,基于交叉学科的新方法引入可以极大地丰富现有的研究手段,帮助我们理解细菌生物被膜这一复杂的生物体系。
