In China, several researchers have come up with top-notch robots that can deliver drugs to tissues. The first delivery was conducted in mice brains to tackle certain tackle certain tumor growth. These scientists achieved this by coating these robots in e.coli created from the bloodstream of these mice. With this in place, the mice will absorb the robots. This helps in fighting cancer effectively and getting rid of tumors.
However, the question remains, what are microscopic drug-carrying robots?
All you need to know about these drug carrying robots.
It’s obvious that the best way you fight tumors and cancer is by targeting the right tissue but surgery can be quite risky, so researchers decided to find a way to improve the delivery of drugs to cure the tumors.
They came up with these robots that are microscopic but can deliver drugs to the tissues in the mice brain and cure tumors. The challenge was to look for means to surpass all the barriers situated in the body which will consist of dense tissue that often forms an obstacle in the movement of these microbots. However, previous studies that have been published in journals led to the research that showed how liquid-coated Nano-robots could be remotely propelled through the eyes of plasmic fluids.
To overcome this, scientists constructed the microbots with magnetic core materials to make it work better. To pull the micro-robots around remotely, they used a rotating magnetic field that was created. With the use of that technology, the team was able to develop a remote controlled hybrid bot. The name given to this design is “neutrobots” because of their ability to enter the cerebra vortex via the casing of the neutrophils.
Several Challenges associated with the Neutrobots.
Scientists say that one of the major problems they faced was achieving a swarm intelligence of neutrophils with the capability of enabling sophisticated complex task accomplishment. Because of this researchers spent eight years developing robots which helps to bridge the gap between the mice’s bloodstream was located in the tail where it was injected and the brain where the tumors emerge from in the brain glial cells.
Another major obstacle that the team overcame was the difficulty of how the cells in the mice couldn’t accept robots. The solution for this was to coat the wings and body parts of these bots with E.coli substances, which are easily recognized by the white cells as foreign invaders. Thus, the robots become palatable for the white blood cells to attack and absorb the robots. These robots get into the mice brain and roll the cells around. After some trial and error, the robots were able to successfully deliver the drugs used for cancer fighting to the intended target tumors.
The team of researchers that developed these robots says that they are not exclusively made for the treatment of glioma and overtime, with extensive research and funding, it is capable of becoming a platform used for good therapy delivery and treatment of several chronic diseases.
