Nano heating will become a new solution to increase the lifespan of transplanted tissues

In the field of organ transplantation, time is of the essence. Because the quality of transplanted tissues decreases rapidly during the transfer process. Now, researchers at the University of California Riverside have taken an important step towards increasing the lifespan of these tissues by developing a new technique called “nano heating”. In traditional methods, transplanted tissues are kept at a very low temperature before transplanting to minimize their cellular activities and reduce the need for oxygen. But these methods face challenges such as tissue damage due to sudden heating during melting.

According to the medical and health news service of Tekna Technology Media, researchers in this research have presented a new method for fast and uniform melting of frozen tissues. In this method, magnetic nanoparticles are injected into the tissue along with antifreeze agents. Then by applying a magnetic field, these nanoparticles are heated and uniformly melt the tissue. This method minimizes the risk of tissue damage due to heating from inside the tissue.

Yadong Yin, the head of this research, in a conversation with Interesting Engineering, said: “Unlike traditional heating methods that are done from outside the tissue, in nano heating, nanoparticles directly generate heat inside the tissue, and in this way, faster heating and It will be more uniform.”

In this method, first, magnetic nanoparticles are produced in the form of very small rods and then they are added to the tissue along with protective agents. The tissue containing nanoparticles is frozen in liquid nitrogen and then by applying a magnetic field, the nanoparticles are activated and melt the tissue. By providing a safe and effective method for thawing frozen tissues, the nano-heating technique can create a huge revolution in the field of organ transplantation. By increasing the life span of transplanted tissues, this technique increases the chances of transplant success and allows more patients to live again.
