Microscopic Robots

Tiny robots small enough to fit into the human body have been developed by researchers for various purposes, including the treatment of cancer, the supply of drugs, and the growth of new cells and tissues.


Physicians are often faced with the challenge of micro-vascular surgery, tissue transplantation or amputated States unite repair. These procedures are very complex, and surgery is often not the most effective solution, because it's very invasive and difficult. Soon, many surgeons apply to nanotechnology and the delicate tasks remote control of small robots, similar in size to a grain of rice that could travel through the body.

In Tohuku University in Japan, an electrical engineer Kazushi Ishiyama and his group designed small screws that can swim through the veins of the body. Potentially can hide tumors to kill them or deliver drugs to the organ or tissue. Why are so small, they can be injected into the body with a standard hypodermic needle, and once inside, can be magnetically directed into the body by a provision in 3D magnetic field and controller. Ishiyama believe that these devices would be particularly useful for removing brain tumors, because they are difficult to manage.
Other Micro Bots create not just machines. Several institutions have participated in the integration of living organic tissue with inorganic components to create hybrid devices that are part of the machine, a part of the body. The first of these devices are driven by self-assembly Microbots life of the heart muscle, created by engineers at the University of California at Los Angeles (UCLA). Each robot consists of a small arc of gold attached to a sheath of cardiac muscle cells of rats, and if released into the body, feeding on blood glucose for energy to move. Testing of the Micro Bots, the researchers involved in a protein-sugar solution to mimic conditions in the body. As the heart muscle contract and then relax, Microbot can be seen as "walk" forward.

This Micro Bots may be used in micro surgery, for example cleaning the accumulation of plaque in the arteries. Technology also has the potential for new legs or fingers to create amputees, allowing cells to grow new muscle on the bones artificially.

But research into the various methods is still in its infancy and there are many problems to overcome. The robot created by researchers at UCLA can only move in one direction and not easy to control. I am now waiting to see whether skeletal muscle is used instead of the heart muscle could help robots move more freely to the heart muscle seems to beat his own pace and it is difficult to control. Using electricity to stimulate skeletal muscle, researchers to enable the robot to turn inside out, and extending the use of renewable energy for the body or mini plants small electricity generators that power the integrated circuits of the computer .
