Release date: 2017-03-20 Recently, the anti-cancer army has ushered in a new force. The Science and Robotics magazine published a new research result. Researchers use magnetic fields to remotely control magnetic micro-robots to perform "work" in the human body. . Separate task divisions are different In the past 10 years, magnetic technology has not only been widely used in the industrial field, but also won a place in the medical field - using magnetic force to remotely control medical devices in the human body. For example, a magnetically assisted remote control catheter system can be used for simple intravascular operation; or a magnetic capsule can be used to guide a capsule camera in the examiner, by implanting a permanent magnet in the "capsule", a magnetic field is set outside the patient, and a gravitational force generated by the magnetic field is generated. Guide the capsule camera to the area you want to check. In addition, there have been studies on the use of magnetic fields to simultaneously control small groups of small magnets. It stands to reason that if you can "command" such a team of micro-robots, you can play a huge role in helping to treat major diseases such as cancer. However, leading such a special team is not simple, requires a strong strategizing ability, and knows how to "transfer troops." However, relying on the magnetic command team is really a huge challenge. We all know that the magnetic field can affect all objects in the range. If these objects have the same nature, then it can only be a slap in the face. "Hula La" is going in one direction, and it is difficult to give orders separately. In order to solve the problem of individually commanding “team membersâ€, these micro-robots can be moved in different directions at different speeds. Researchers from the Philips Research Institute in Hamburg, Germany have developed a new method that can be used in an identical spiral robot team. Control any member in the middle to enable it to perform special tasks individually. "Our technology allows micro-robots to perform complex operations inside the human body," said physicist Jurgen Ram, the first author of the study. Controlling by the magnetic field is similar to catching a doll First, Ram's team created many identical spiral robots, and then fixed the spiral robots with a powerful, uniform magnetic field. There is a hole in this powerful magnetic field, and micro-robots are relatively "free." By using this free point, superimposing a relatively weak, gentle rotating magnetic field on a large magnetic field can control the rotation of the spiral robot in the free point without affecting other "teammates". In addition, the researchers can adjust the position of the free point by adjusting the large magnetic field, so that there is a function like "catch the doll machine", and you can freely select a single robot. In the experiment, the researchers succeeded in having several spiral robots rotate precisely in different directions at the same time. The research team pointed out that in theory they can manipulate hundreds of micro-robots simultaneously. "Some people think of using the principle of screw drive, so that the micro-robot does not rely on batteries or motors to perform some operations in the human body," Ram said. Micro robots are especially useful After mastering this advanced "dispatching array", the researchers have already thought of a series of "workplaces" that can make this team show their strengths. One is to equip the injectable micropill with a micro-helical robot. The doctor can use the magnetic field to remotely control the auger, "command" its rotation to open the pill to release the drug. Using this method, doctors can ensure that drugs containing radioactive components "stare" at the tumor and destroy it without affecting the surrounding healthy tissue, thereby reducing side effects. In addition, once the drug releases the desired therapeutic dose of radiation, the physician can use a magnetic remote to close the pill. The pill is made of a metal material to have the property of preventing leakage of radioactive materials. Still another is the case involving implants, such as orthopedics, which can change over time. For example, as the patient recovers, the physician can use magnetic force to change the shape of the implant to better accommodate the patient's size. According to Ram's vision, in the future, researchers will be able to develop smaller magnetic field devices for controlling micro-robots. At the same time, the use of X-ray machines or ultrasound scanners and other imaging techniques to accurately locate the "workplace" of these micro-robots. Anti-cancer "Thirty-six" Increase defense - let the immune system do it yourself In addition to the "helpers" that scientists have painstakingly found for us, can we humans work hard? Be aware that our own immune system is a very powerful and complex existence that recognizes and destroys the infinitely infinite “face†of intruders. After understanding the interaction between cancer and the immune system, the research team is working hard to develop new therapies that mobilize the body's natural defense potential, and call it immunotherapy. Strong combination - antibody antigen kills cancer cells When our body is infected by foreign cells such as viruses or bacteria, the immune system responds immediately. The resulting antibody binds to the protein-antigen on the surface of the foreign cell. Sometimes this process is sufficient to neutralize foreign cells. In other cases, the antibody and antigen bind to "mark" the cell as a target for the elimination of T lymphocytes. Immunotherapy can "train" the immune system to produce antibodies that bind to cancer cell antigens, thereby preventing the growth of these antigenic proteins, or labeling cancer cells as targets destroyed by immune cells. Introducing foreign aid - using drugs to stimulate the immune system One of the promising ones in immunotherapy is the synthetic monoclonal antibody. These drugs can "entangle" cancer cell antigens and mark them to die. Although antibody-mediated therapy has some promise, this drug is not the best policy, and the price of more than 100,000 US dollars is an unaffordable treatment for most cancer patients and families. Self-reliance - using vaccines to fight cancer cells Researchers at the Ohio State University Comprehensive Cancer Center at the Arthur G. James Cancer Hospital and the Richard J. Solove Institute, as well as other institutions around the world, are investigating single-needle vaccines that trigger the same mechanism. By designing a synthetically synthesized protein into the body by vaccination or immunization, the immune system can be trained to recognize the antigen of the cancer cell. Compared to antibody-mediated therapy, this method is "cheap and inexpensive", and an effective vaccination can give patients years of "combat power" at a cost far below $1,000. Attack with poison - release the virus army to attack In addition to the above methods, the researchers realized that they can train viruses to fight cancer, and this approach has a double benefit. These oncolytic viruses can directly attack cancer cells and can replicate in large amounts in diseased cells, causing the bursting of diseased cells. Like vaccination, oncolytic viruses create a long-lasting, robust defense system that trains the immune system to attack cancer cells in months or even years.
