研究介绍 

Research Interests


实验活性软物质 

1. 活性物质如分子马达驱动的微管、细菌和微纳米机器人,通过自身或外场驱动进行活性布朗运动。当密度足够高的时候,活性物质形成集体运动;同时,活性物质整体的力学和材料性质,例如粘弹性也会变化,出现活性“湍流”和“超流”等现象。课题组关注活性粒子的奇特运动规律,结合微流控系统和高速摄像机,观察活性粒子在外场和空间限制条件下的运动规律。同时通过光学镊子和原子力显微镜直接测量推进力变化,理解活性物质涌现现象的微观机制;2. 浸润和催化反应对活性物质运动的影响:通过原子力显微镜和光镊研究活性物质跨越不同时间和空间尺度的动力学,探索基于催化反应的新型活性物质。3. 活性粒子运动的统计物理规律:通过高速成像,追踪单个活性粒子的运动轨迹,统计其随机运动规律,探索力、光、电等能量势场下活性物质的统计力学规律。

Active Soft Matter: 

1. Statistical physics of active particles such as swimming bacteria and Janus partiles. By directly observing trajectories of a single active particle and analyzing the statistics of their random motion, we explore the statistical physics of active matter under influence of force, heat, light and electric potential; 2. How spatial confinement affect motions of microswimmers? We study the locomotion of a bacterium by its flagellum using a combinational tool of optical tweezer and  high speed video microscopy ; 3. How interface and wetting affect the collective motion of active matter? To tackle this question, we use atomic force microscopy (AFM) and optical tweezer to study the dynamics of active matter at interfaces on multiple scales in time and space.
