Mexico: Research is being done on blood all over the world and work is being done to increase its usefulness through artificial biology.
The latest news is that scientists have artificially created red blood cells (RBCs) with many other properties added. With this invention, not only can oxygen be sent to any part of the body through red blood cells, but special drugs can also be sent. In addition to identifying toxic components, these cells will be able to do many other things.
We know that red blood cells play a very important role. They carry oxygen from the lungs to all the cells and tissues in the body. The role of hemoglobin is very important in that protein and steel are linked to oxygen molecules. Medically, RBC also has many self-defense features that allow them to do their job. They shrink and expand, pass through very thin blood vessels, do their job and stay in our body for a long time.
Although there have been previous attempts to make red cells, there has been little success in replicating all of their properties. But now the University of New Mexico, the Cindia National Laboratories and the South China University of Technology have developed artificial blood cells that can do all the work of real cells, as well as other things.
For this, the experts first studied the original cells that were taken from the human body. The cells were first coated with a very thin layer of silica, followed by a layer of polymer with both positive and negative charges. The silica was then removed and all the cells were covered in a natural layer on top of the RBC.
In this way, many blood cells with the same charge, protein, size and properties were formed. In experiments on mice, they proved to be the best and naturally shrunk and shrunk and passed through tiny ducts. They circulated in the body of rats for 48 hours and no side effects were observed.
In the next test, cancer cells, hemoglobin, toxins sensors and magnetic nanoparticles were successfully added to the cells. In this way, a cell can perform a number of functions, such as delivering medicine, identifying hazardous compounds, and performing other functions.
However, in the next stages, they will also be tested on humans, but its destination is still far away.
