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.

该项目的目的是在细胞水平上测量力学，使用光镊测量细胞周围/内部的纳米级环境，并使用光片显微镜进行成像。该项目预计将产生有关细胞在其环境中运动的新知识，这些知识与集体行为有关，这对理解感染和生物膜的形成至关重要。预期的成果包括加深对从阿米巴到人类的一个神秘过程的理解，通过这个过程，细胞通过“吞咽”液体来“吃喝”，并通过降解蛋白质和细胞碎片来补充营养摄入。它将产生这些过程的新知识，以更好地了解力学如何影响细胞生命。
