Image (IMAGE) CNRS Caption Image of a lysosome observed using transmission electron microscopy, a method that can reveal the form of nanoparticles inside of cells. The degradation products are made up of gold crystals measuring 2 nm in diameter self-organized in nanoleaves. Non-degraded nanoparticles are in red, and degradation products are in orange.
