Nanotechnology offers the unprecedented and paradigm-changing
opportunity to study and interact with normal and cancer cells in real
time, at the molecular and cellular scales, and during the earliest
stages of the cancer process. Through the concerted development of
nanoscale devices or devices with nanoscale materials and components,
the NCI Alliance for Nanotechnology in Cancer will facilitate their
integration within the existing cancer research infrastructure.
