cancer has become a foremost cause of death around the world. Cancer is
an extremely complex disease to understand because it entails multiple
cellular physiological systems such as cell signaling and apoptosis.
However the most cancer treatments are limited to chemotherapy,
radiation and surgery.
Even in these scopes, different drawback plays major role shortcoming its affectivity. 99% of chemotherapy does not reach the cancer cells, US National Cancer Institute (OTIR, 2006). Moreover poor drug delivery and residence at the target sites reach o significant complications including multi drug-resistance.
Radiation therapy is also not specific to cancer cells. Most of the normal cells in the body die at 460 C (1080 F) which limited the extent of affectivity of radiation therapy. And most of times surgery is possible if cancer is detected at early stages.
Nanotechnology has the power to offer solutions to these current obstacles in cancer therapies due to its unique size (1-100 nm) and large surface to volume ratios. Currently, lots of research is going on to design novel nanodevices capable of detecting cancer at its earliest stages, pinpointing its location in the body and delivering anti-cancer drugs specifically to malignant cells.
