Red light forces cancer cells to suck up drugs - health - 13 November 2010 - New Scientist
To overcome this problem, Andrei Sommer at the University of Ulm in Germany and colleagues exposed cells to pulsed red laser light. Light of this wavelength decreases water density and pushes water out of the cell. When the laser is switched off, the water returns to its high-density state, forcing the cell to "suck in" water and any other molecules, including drugs, from its surroundings.
