Cancer nanotechnology

Nanotechnology is the engineering of functional system at the molecular scale which may exert a revolutionary impact on cancer diagnosis and therapy. Nanotechnology is being applied to cancer in two broad areas: I] the development of nanovectors such as nanoparticles which can be loaded with drugs or imaging agents and then targeted to tumours, and ii high-throughput nanosensor devices for detecting the biological signatures of cancer. Combined, such technologies could lead to earlier diagnosis and better treatment for cancer patients
