A new method to recognize cancer cells based on the implantation in the body of tiny spherical tanks made from synthetic polymers called dendrimers (from the Greek. Dendron - tree). These polymers were synthesized in the last decade and have a new, no coherent structure, which resembles the structure of coral, or wood. Such polymers are called sverhrazvetvlennymi or cascaded. Те из них, в которых ветвление имеет регулярный характер, и называются дендримерами. As the diameter of each sphere, or a nanosensor, is only 5 nanometers - 5 billion of the meter, which allows for a small area of space billions of such nanosensorov.Once inside the body, these tiny sensors to penetrate the lymphocytes - white blood cells, providing a protective reaction of the body against infection and other disease factors. In immune response, lymphoid cells of a certain disease or environmental conditions - cold, or exposure to radiation, for instance - the cell protein structure changes. Each nanosensor is covered with special chemicals, when such changes begin fluorestsirovat or shine.To see this light, Dr Baker and his colleagues are going to create a special device, scan the retina The laser of the device must zasekat luminescence of lymphocytes, which are one after another, pass through narrow capillaries eye If a sufficient number of lymphocytes is marked sensors, then to identify the damaged cells need to be 15-second scan, the scientists say.
