The project aims to measure mechanics at the cellular level using a combination of optical tweezers for measurement of nano-scale environment around/inside cells and light-sheet microscopy for imaging. The project expects to generate new knowledge about movement of cells through their environment, relating to collective behaviour which is of importance in understanding infections and formation of biofilms. Expected outcomes include deepened understanding of an enigmatic process conserved from amoebae to humans, by which cells ‘drink and eat’ by ‘gulping’ fluid and supplement their nutrient intake by degrading proteins and cell debris. It will generate new knowledge of these processes to better understand how mechanics affects cellular life.

该项目旨在结合使用光学镊子测量细胞周围/内部的纳米级环境和用于成像的光片显微镜来测量细胞水平的力学，该项目期望产生有关细胞在其环境中运动的新知识。与集体行为有关，这对于理解感染和生物膜的形成非常重要，预期结果包括加深对从变形虫到人类的神秘过程的理解，通过该过程，细胞通过“吞咽”液体来“喝和吃”。通过降解蛋白质和细胞碎片来补充营养摄入，它将产生有关这些过程的新知识，以更好地了解力学如何影响细胞生命。
