Switching on a light and understanding and controlling the internal dynamics of a cell — the Dimova Group has succeeded in doing so. The team irradiated cell replicates with different colors of light and thus changed the interactions between the cell elements. Controlling these complex processes could make it possible to deliver drugs specifically into cells in the future. At the push of a button, this administration could be adjusted or even reversed, which could revolutionize the treatment of cells in an intelligent, precise and non-invasive way.
