Abstract: Human beings want to live long healthy, pain-free lives. We will continue to create new ways to do so. Nanotechnology is an emerging technology that can help us along that path. It won’t enable humans to shrink, but it can, however help us to modify and create particles that circulate through the body with more control. Increasing the amount of toxic drugs eventually kills the patient .The main reason for this happen is bioavailability. This paper fully explains the way to get drugs to a specific site in the body that is to increase the bioavailability.

If the anticancer drugs are pumped through the body it will kill not only cancer cells but also healthy cells. If we can deliver the drugs directly to the cancer cells, it limits the side effects. This benefit is our motivation. There is a significant clinical need for novel methods for detection and treatment of cancer which offer improved sensitivity, specificity. In recent years, a number of groups have demonstrated that photonics-based technologies are valuable in addressing this need. In this paper we are using the nanoshells for cancer treatment which is more effective compare to other modern technologies.
