A team of scientists has created synthetic red blood cells that could be more useful and effective than natural ones in curing diseases. Initial results show that are capable of performing all the functions of natural blood cells and much more.

Nanotechnology has among its main objectives the promotion of medicine. Scientists want to introduce tiny devices or robots that Serve as medicine or explore the body without being so invasive like current techniques.

This new research with red blood cells has been carried out between the University of New Mexico, Sandia National Laboratories and the University of Technology of South China. The study published in the Nano journal of the American Chemical Society, reveals that artificial red blood cells could be a new treatment for cancer.

The technological revolution has changed the world forever and, in the coming years, our way of understanding and relating to medicine will radically change.

These artificial cells have been created by covering donated red blood cells with a thin layer of silica and another layer of polymers with positive and negative charges. By later coating them with natural red blood cell membranes, white blood cells do not identify them as invaders, nor attack them.

Tests have first been carried out on bird embryos and mice where it has been detected that these nanobots can remain in the blood of the animals for up to 48 hours, successfully carrying out the functions assigned to them. They can transport oxygen, medicines or loads thanks to its magnetism.

Until now, artificial red blood cells only managed to imitate some of the qualities of their natural versions, but this new design has both the size and appearance, as well as the qualities of natural blood cells and some extras.

Lets remember that red blood cells are disk-shaped cells with millions of molecules, they are very flexible and contain hemoglobin, a protein with iron that makes oxygen stick to them to transport it through the blood.

The new artificial blood cells they are just as flexible to pass through the capillaries and return to their shape. But in addition to all these qualities, they are able to administer medications and transport magnetic nanoparticles to carry loads throughout the body. Its creators bet that their invention has future medical applications in fighting cancer and biodetection of toxins.
