A Study On Carbon Nano Tube Based On Drug Delivery

Abstract

According to WHO (Word Health Organization) in 2005, about 7.6 million people died of cancer out of 58 million deaths worldwide. The traditional drug delivery system (e.g., radiation therapy, chemotherapy, surgery etc) used in cancer treatment has many side effects. Sometimes it damages normal cells near the area where therapy is used to kill cancer cell and become toxic when it crosses the permissible limit. Recently the SWCNTs (Single Walled Carbon Nanotube) has gained much attention for targeting drug delivery system because of its unique properties. In this case the fictionalization of SWCNT is a key in developing SWCNT based drug delivery system. We studied and found that surface area of armchair SWCNT is greater than that of zigzag SWCNT, and armchair gives more sites for fictionalization than zigzag. For fictionalization more sites means more or equal drug carrying and less use of SWCNT. As a result fewer side effects and less toxicity will be occurred in the normal cell in SWCNT based drug delivery system.
