Application of nanotechnology in cancer: a review.

Cancer nanotechnology is an interdisciplinary area with broad applications. The basic rationale is that nanometre-sized particles, when linked with tumour-targeting ligands, can be used to target tumour antigens. It is difficult to target the abnormal cells in cancer by the conventional method of the drug delivery. Nanotechnology is probably the only method that can be used for site-specific action without causing the side effects. Different cancer detection techniques like Carbon Nanotubes (CNTs), nanorods and biosensors are available. This review paper gives an idea about the possible potential of nanotechnology in drug delivery, drug targeting and diagnosis of cancer.
