Nanomedicine could one day provide a wide range of treatments, but possible toxicological effects from nanoparticles are still a cause of considerable concern. Studies have shown that nanoparticles tend to accumulate in the liver and spleen, but until now there have been limited ways to monitor the exposure of these organs without taking a sample from the tissue itself – which could be fatal. Now, researchers at the University of Toronto have demonstrated that a glance at the skin can reveal the level of nanoparticle exposure and that measuring nanoparticle content in a skin sample can quantitatively indicate the concentration within internal organs……..
