A team of international scientists are developing nanoparticles that may aid in deep-tissue optical imaging. These new photoluminescent nanoparticles absorb and emit infrared light and can shine through over three centimeters of tissue.  In multiple tests, scientists were able to obtain high-contrast images of particles through the thick biological tissue. In the future, researchers hope to study the use of these nanoparticles in targeting cancer cells or other biological targets.
