Nanotechnology is the science that refers to the interactions of cellular and molecular components and engineered materials typically clusters of atoms, molecules, and molecular fragments at the most elemental level of biology. Nanoscale devices have the potential to radically change cancer therapy for the better and to dramatically increase the number of highly effective therapeutic agents. Cancer is leading cause of death in world. Nanoparticulate technology can prove to be very useful in cancer therapy allowing for effective and targeted drug delivery by overcoming the, many biological, biophysical and biomedical barriers. Different types of Cancer cells have unique properties that can be exploited by nanoparticles to target the Cancer cells. Nanoparticles can be used to monitor (by utilizing or adding optic, magnetic, and fluorescent properties) and to treat Cancer (by Heat ablation, chemotherapy, gene therapy). Nanotechnology is a multidisciplinary field convergence of basic sciences and applied disciplines. Its definitely a medical boon for diagnosis, treatment and prevention for cancer diseases. Gold nanoparticles (AuNP’s) have also been exploited for their potential application in treatment of cancer cells. No human trials have been performed yet and human trials are still at least a few years away.
Key words: Nanotechnology, cancer, nano devices, biomedical barriers
