New methods for identification and treatment of cancer cells are continued to be researched. Colon cancer, one of the leading causes of cancer death in the United States, has been used as the choice for the cancer to identify and treat in certain studies. Through previous experiments, treatments for people with colon cancer have been utilized but still present issues associated with the treatment is the proper identification of cancer cells and the high toxicity associated with some of the treatments and the effect on the human body. Research into procedures to reduce the identification time of cancer cells and lower the exposure to toxic chemicals in the body led to scientists modifying the delivery of the identification markers and treatments with nanotechnology. Nanoparticles are seen as a viable solution to these problems and its use with identification of cancer cells and treatments were researched and reported to be analyzed for future use. Nanoparticles have been shown to be at times 20nm in length2 and have a high effectiveness for diffusing encapsulated treatments. Up to 85% effectiveness has been reported in some cases2. The small size of nanoparticles also allow the ability to control what interactions take place by what is encapsulated or what is used to encapsulated the particle. Their uses identifying and treating colon cancer cells were reported by Nanoletters and Cancer Prevention The use of nanoparticles as labeling agents in immunoassays, which are tests that use antibodies to detect specific molecules, offers an improvement in sensitivity over traditional enzyme or dye agents. When combined with specific antibodies, it was reported that nanoparticles can target tumor-expressed proteins with high affinity and ... ... middle of paper ... ...ounds required to affect the cancer cells. The information shows that nanoparticles are a viable target delivery system for treatment of cancer cells within organisms. They require lower dosage amounts to treat the affected cells as they can be constructed to release in specific environments such as a specific pH located in the body or when another compound is around. Needing only the required amount to treat the cancer allows for only the needed amount of the drugs to enter the body and the limit toxic exposure. This will effect not just current treatment options, but past treatment ideas that had a high chance of causing harm to people because of their high toxicity might now is viable to be tested with nanotechnology. With further research into nanotechnology, the use of nanoparticles in chemoprevention for humans could become a treatment option in the future.
