Article Summary
Nanomedicine is a hugely promising field, but while remarkable new treatments and diagnostic tests are being developed, questions remain about the long term effects of nanoparticles on our bodies. Adding to our understanding of these issues, researchers have now reported that the use of quantum dots - tiny luminescent crystals that can be used to monitor disease at a cellular level - appears to be safe in primates over a one-year period.
