![Fluorescence: a tool to study molecular dynamics in biology
Fluorescence is used in Biology as a tool to study the internal of cells. In this video, Rémi Berthoz explains the basics of interactions between light and matter to schematically describe how fluorescent molecules can be used to monitor the flow of calcium ions in living cells. Watch Rémis video to learn more.
Rémi Berthoz is a student in the Cell Physics Master at the University of Strasbourg, France.
