Nanotechnology, could possibly in a decade, change the basic concepts of cancer diagnosis and treatment. Nanoparticle science is considered the foundation on which most nanotechnological cancer therapies are based. A Nanoparticle (NP) possesses unique properties like quantum effects and surface area effects. The NP circulates through the body, detects cancer associated molecular changes, assists in imaging, releases the therapeutic agent and monitors effectiveness of the intervention. Cancer research has seen improved efficacy and decreased toxicity of chemotherapeutics because of nanotech formulations. This paper overviews the basic concept, advances and prospects of nanotechnological applications in cancer prevention, detection and treatment.
