Researchers in the Department of Bioengineering at the University of Illinois have recently shown that photo luminescent CNPs can display a reversal of their optical properties in cancer cells. This reversible switching of photoluminescence (PL) is possible by counterionic caging and decaging of carbon nanoparticles at the nanoscale.
