Nanotechnology is a science that deals with the use of material at nanoscale (10^-9 metre). Nanotechnology applies in dosage form design provide various advantages like increased solubility, enhanced dissolution rate, increased stability, increased bioavailability so rapid onset of action. It gives great opportunities in pharmaceutical field. There is tremendous potential and scope of nano based drug delivery system in near future. This review includes types of nanoparticles, nanotechnology in drug delivery system, their application, commercially available nanoparticles, current and future prospective of pharmaceutical nanotechnology.

Cancer is responsible for millions of death across the world. There are so many medicine developed but still required to developed more advanced cancer therapy. Various technologies are developed which are under clinical trials or already into clinical practice. Therefore, development of rationalized and individual therapy is required. In this review we will provide detail description of recent innovation in cancer therapy by various surgery and recently discovered drug via chemotherapy.
