Attaching tiny diamond chips, just slivers of carbon really, to nanoparticles helps to shrink lung tumor cells in animal models, according to recent research by Ho et. al. in the latest Science Translational Medicine. Scientists created small nanoparticles with attached diamond specks and the chemotherapeutic agent, doxorubicin (dox) and injected them into mice with lung cancer. These nanoparticles zoomed in on their target, the cancerous tumor, without causing any auxiliary toxicity that is seen when dox is just injected directly into mice. Therefore, higher doses of dox could be given without having liver toxicity or other side effects.
