Scientists who conducted biological research, have created a "zombie" cells, the functionality of which is greatly increased after their death. The formation of this type of cells is made possible by the use of silicic acid.
Biologists from the University of New Mexico, USA, have developed an innovative technique that allowed to create a "zombie" cells. Scientists were mixed in a petri dish organic matter and silica, resulting in them to obtain cells coated silica.
According to lead author of the study — Michael Hess — silica acts as a permeable armor that is almost an exact copy of the cell structure. The design of silica looks like a living cell, but can withstand the pressure and high temperatures, disastrous impact on mikroogranizmy.
Thus, at a temperature of 400 degrees Celsius, the protein is evaporated from the cell, but is silicon dioxide, which is a three-dimensional copy of the previously living being.
"The difference is that instead of modeling a person, say, a famous criminal, we will be able to display its internal structure and function. And this will help us hardened silica cells. Also this valuable biological material can be converted into reusable resources, which can be used in a fuel cell, sensor technologies, and in the process of cleaning up, "- said Michael Hess.
Biologist colleague Brian Keyhr said that should distinguish the concept of mummification and "zombie" technology.
"Our process went without mineralization and fossilization. "Zombie" cells — a kind of chemical and biological bridge between forms that were alive, but they were able to preserve its functionality in the future ", — concluded the experiment Keyhr.
At that time, the American researchers are "resurrection" of microorganisms, Scottish scientists are trying to print to a printer dimensional embryonic stem cells (ESC) rights.
As previously reported on FederalPost, experts from the University of Edinburgh used biochernila containing ESCs to create 3D-viable cells.
May soon scientists will be able to print on the 3D-printer, heart, liver or kidney.
