Kinetic (very rapid) vitrification (KVF) is a very promising approach in cryopreservation (CP) of biological materials as it is simple, avoids lethal intracellular ice formation (IIF) and minimizes damaging dehydration effects of extracellular crystallization. Moreover, achieving the ultra-high rates, which would prevent IIF during cooling and devitrification during resuscitation, and achieve KVF for practically any type of cells with one protocol of cooling and re-warming would be the “Holy Grail” of cell cryobiology [3]. However such hyperrapid rates currently require very small sample size which, however, is insufficient for many applications such as stem cells, blood or sperm. As the result, even smallest droplets of 0.25 microliters cannot be vitrified sufficiently fast to avoid the use of potentially toxic external vitrification agents such as DMSO or EG due to the Leidenfrost effect (LFE). In this presentation, we describe an entirely new system for hyperfast cooling of one-two order of magnitude larger samples that we call “KrioBlastTM”, which completely eliminates LFE. We have successfully vitrified up to 4,000 microliters of 15% glycerol solutions, which theoretically corresponds to the critical cooling rate of hundreds of thousands °C/min. We believe that such a system can revolutionize the future cryobiological paradigm.

Leidenfrost Effect

We review studies of levitating droplets over liquid–gas interfaces and dry solid surfaces with a focus on the physical mechanisms of levitation under different conditions. A fascinating physical phenomenon of self-organization of levitating droplets into large arrays is described and explanations for this unusual behavior are reviewed. Closely related topics of nonisothermal flotation and levitation of evaporating droplets over a pool of nonvolatile liquid, as well as recent advances in the study of the Leidenfrost effect, are also discussed.
