Nano Technology and Cancer

It has been found that nanoparticles can be used to cure cancer, spheres of nanomaterials coated with gold have to be injected in a patient showing cancerous tumours. These nano scale particles travel through blood and seep into tumours and collect there. Infrared light is used to detect the location of these tumours and then a certain higher intensity of Infrared light is used to convert this rays into heat by the spheres which destroy the cancerous cells. This technique has most limited side effects and is supposed to cure cancer like prostrate , skin and breast cancer apart from other types of cancers successfully.
