Nanobubbles (1 of 2)

Caption: Identical cells stained red and blue were the target of research at Rice University to show the effect of plasmonic nanobubbles. The bubbles form around heated gold nanoparticles that target particular cells, like cancer cells. When the particles are hollow, bubbles form that are large enough to kill the cell when they burst. When the particles are solid, the bubbles are smaller and can punch a temporary hole in a cell wall, allowing drugs or other material to flow in. Both effects can be achieved simultaneously with a single laser pulse.
