Nano Magnets for Thawing Frozen Tissues
April 25, 2017 | Terry Sharrer
It has long been known that freezing tissues, such as arteries, extends their “shelf life” for transplantation, but problems arise when cryopreserved tissue has to be thawed with convective heating. Rewarming can produce crystals and cracks in the tissue. However, researchers at the University of Minnesota have found that by adding magnetic nanoparticles to the cryopreservation solution, and then reheating by means of inductive radiofrequency, more of the tissue (human fibroblasts, porcine arteries, and porcine heart muscle) remains viable than that thawed with convective heating.
