South Korean scientists have transformed leukocytes in the microrobot to fight cancer

Scientists sometimes create such inventions, learning about the existence of which their formulation simply does not fit in the mind. For example, I would never have thought that the white blood cells can be transformed into mechanical microbots. But South Korean researchers at Chonnam National University, headed by Professor Park Suk-ho, not only did these microbots, but also to "teach" them to fight tumors.

Koreans created micro-robots, which are the world's first of its kind, can effectively deal with all cancers, including colon cancer, gastric cancer, breast, liver and pancreas.

Despite the seemingly fantastic that blood cells can create a microrobot, the process of production is actually quite simple. Using aggressive nature of leukocytes and macrophages, the researchers forced them to "eat" a large number of nanoparticles filled with anti-cancer drug treatment. Thus leukocytes become a means of delivering a drug target, which raises the efficiency of the drug several times

Similar studies were conducted in the past. But the method was a pre-existing flaw molecule drug do not penetrate into the interior regions of tumors, where the most intensive maximum division of malignant cells. For this purpose, and the magnetic nanoparticles are used which are under the influence of an external magnetic field directed leukocytes and macrophages in any area of ​​the tumor.

Thus, the use of immune cells as micro robots provides simultaneously carrying out spot chemotherapy and immunotherapy of cancer, which is one of the most effective methods of combating cancer today.
