Gold-centered nanospheres have been show to be administered safely by two routes in a mouse study led by investigators at the Stanford University School of Medecine. This is the first step that would allow further studies into nanotoxicology possibly leading to clinical trials within a year and a half.
This study brings hope for using nanoparticulate detectors for cancerous lesions, which would be a great step forward for early detection of cancer. It is important to perform nano-toxicological experiments as the safety of administering these interventions is one of the most important concerns that needs to be addressed before any Nanotechnology can be administered to humans. This study shows promising results indicating that this may be a viable pathway to enhance cancer detection at the cellular level.
It is assumed that a cellular detection of cancerous cells would allow for swifter clinical intervention into the disease. Thus allowing a reduction in the subsequent mortality associated with the disease. As of course with most cancers the early they are found and treated the more likely a person is to survive.
