Is Nanotechnology Ready for Primetime?
| The first 150 words of the full text of this article appear below. |
In October, the National Cancer Institute made its first nanotechnology research awards worth $33.3 million to 12 research groups and seven hubs. A month later, at the Molecular Targets and Cancer Therapeutics meeting in Philadelphia, a press conference devoted exclusively to nanotechnology highlighted several experimental studies using nanoparticles, including a liposome–nanoparticle gene therapy designed to home in on and kill cancer cells wherever they are throughout the body. Nanotechnology's potential application to cancer seems to be in the news almost weekly, with new uses of the technology for diagnosis and treatment moving rapidly from the lab toward clinical trials. But along with several promising discoveries have come unanswered questions about nanotechnology's safety for human health and the environment.
Since the discovery of carbon nanotubes and their unusual properties in 1991, the hope for and hype of nanotechnology's potential to better diagnose and treat cancer have blossomed. In September 2004, the
