Russian Scientists Found A Way To Cure A Myocardial Infarction In A Few Months
A new approach to organ regeneration, which has no analogs in price and efficiency, was developed by scientists Of the national research University "MIET." The material they created, as explained by the authors, will restore heart tissue after a heart attack in just two to four months. The data is published in the journal Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy.
MIET specialists for the first time in the world, according to them, managed to find a way to chemically bind carbon nanotubes with molecules of the most common blood protein — albumin. The physical mechanism they discovered allowed them to develop a new method for 3D laser printing of nanocomposites.
"Under the action of a laser, a strong covalent bond occurs between albumin and carbon nanotubes, which makes it possible to print structures of a given shape. Living cells such as connective tissue or myocardium can easily take root on such frames (scaffolds), which makes it possible to effectively restore damaged body tissues," said Alexander Gerasimenko, head of the laboratory of biomedical nanotechnology At the Institute of biomedical systems of NIU MIET.
As the scientists explained, the heart implants they created are three to four times cheaper than Russian and six to eight times cheaper than foreign analogs, surpassing both in a number of parameters. In addition to scaffolds used in tissue engineering, the technology is also suitable for the production of biosensors, microfluidic systems, and even advanced cancer drugs.
"We are able to print a material that is similar in characteristics to heart tissue: it can contract with the myocardium and has electrical conductivity, allowing the heart's bio-currents to pass through. Our method also allows you to regulate the porosity of structures, ensuring the penetration of both living cells and the germination of capillaries and nerve endings," explained Alexander Gerasimenko.
