摘要
Here we use the combination of fluorescent molecular rotors (FMR) and fluorescence lifetime imaging (FLIM) to image matrix viscosity in live cells. We use non-cancerous, epithelial human cornea (HCE) cells as a model system. We find that mitochondrial matrix viscosity varies between individual cells and even between individual organelles, showcasing the potential of viscosity imaging for cell biology purposes.
