COMPOSITIONS FOR DETECTING CELLULAR FORCES

摘要

Described herein are methods and compositions relating to the measurement of the forces exerted by and between cells. For example, the compositions can relate to droplets comprising an optically detectable molecule (e.g. a fluorescent molecule), an inner biocompatible oil layer, and an outer surfactant-transducer layer. The distortion of these droplets by cells can be detected and permits the measurement of the forces exerted by the cells.
