A new way to warm up frozen tissue using tiny vibrating particles could one day help with the problem of organ shortages.
We know how to cool organs to cryogenic temperatures, which is usually below 320 degrees Fahrenheit. But the organs can’t be stored for long — sometimes only four hours for heart and lungs — because they get damaged when you try to warm them up. As a result, more than 60 percent of donor hearts and lungs aren’t transplanted. In a study published today in Science Translational Medicine, scientists used nanoparticles to warm up frozen tissue quickly and without damaging the organs. Within a decade, this could lead to being able to store entire organs in organ banks for a long period of time, the authors say.
