Nanotechnology in Curing Cancer

Nanotechnology is the study consisting on manipulating materials to build devices and structures at a very low level. It is used in approximately all fields, especially the science fields like physics, engineering … This technology is applied also in medicine to cure diseases especially the deadliest ones like cancer. So far, all treatment used to cure cancer has lots of side effects and may end up in a total deterioration of the human body. Therefore nanotechnology can then be used to attack unique properties that can make cancer treatment more effective and safer. So let’s figure out the importance of nanotechnology and how this technology works to heal people from cancer.

Nanoscience is a new interdisciplinary scientific study consisting of both medicine and engineering to manipulate matters and particles at the molecular or Nano-scale. In 1959, the physicist, Richard Feynman, came up with a theory regarding this technology. Nanotechnology remained a theory until 1981, the creation of scanning tunneling microscope. The nanomedicine. the usage of the nanotechnology in the medical fields, is a promising technique to cure the human body of serious threats. Even more, the use of nanoparticle can be useful to repair damaged particles on the molecular level.

Cancer is a deadly disease characterized by the alteration of DNA in somatic cells which result in an uncontrollable proliferation and cell growth. There are over 100 different types of cancer and it can start anywhere in the human body. Depending on the type of cancer, there are many ways to diagnose this disease such as magnetic resonance imaging (MRI), tumor biomarkers analysis and most frequently by biopsy. Up to date, there is no treatment that can completely cure this disease especially in its latest stage; most treatments such as, radiotherapy, chemotherapy, surgery work better in its earliest stage. Unfortunately, most cancer treatments are not selective which results in the destruction of both normal and cancer cells. Therefore, the usage of nanotechnology is very efficient. Using this technology, very small particles, as small as the human cells or even smaller, are injected into the human body and get attached to a specific predefined type of cells. In this situation, the nanoparticles will be attached to the cancer cells and can feed back to a server the location of the defected cells and their type. But of course, that’s not the only purpose of the particles. The doctor can send a command from his computer to those nanoparticles to destroy those cells. The nanoparticles themselves will overheat and will kill the cancer cells.

Nanotechnology is the future in cancer detection and treatment. It is the use of one small device that does everything. This single device with the ability to follow detects and destroys cancer cells. While most conventional methods cannot completely cure cancer, and can even cause side effects. I believe that nanotechnology isn’t by itself a cancer treatment; it is just a way to assist existing treatment methods to enhance their efficacy, selectivity, and safety and to provide a better outcome. Regardless of all the advances in nanotechnology, this study isn’t a cure for cancer, but, it is a significant step towards a better and longer life, it is a forward movement in the fight against this disease that will eventually save millions of lives and make cancer detection and treatment more effective, safer and easier.
