Researchers break nano barrier to engineer the first protein microfiber

Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale - a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.

RF heating of magnetic nanoparticles improves the thawing of cryopreserved biomaterials

Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Now researchers leverage a clinically proven technology platform, in magnetically heated nanoparticles, to overcome this major hurdle limiting further advancement in the field of cryopreservation.
