At the present time, drugs used for treatment of cancer, have side-effects, including degradation of cells and resistant drug. Nanotechnology can overcome these problems and provides basic changes in diagnosis and cancer therapy. Sub-micron systems (i.e. nanosystems) in pharmacy have surged; particularly nanocarriers are important tool for drug delivery. Targeted nano drug carriers provide more efficient drug distribution, intravascular or tumoral administration is discussed as well as the mechanism involved in tumor regression. Generally, nanotechnology as a novel science in biological discipline has a considerable potential in diagnosing cancers and caring them, as soon as possible, increases the hope of human life. In this paper, the different kind of nonocarriers and their role in cancer therapy is discussed elaborately.
