“…The probability of a primary nucleation can be increased by electrofreezing, where a high electrical field is locally applied to a sample [70,76]. Other physical methods to control nucleation include the use of ultrasound [82] or laser light pulses [83], reviewed elsewhere [73].…”

The preservative effects of low temperature on biological materials have been long recognised, and cryopreservation is now widely used in biomedicine, including in organ transplantation, regenerative medicine and drug discovery. The lack of organs for transplantation constitutes a major medical challenge, stemming largely from the inability to preserve donated organs until a suitable recipient is found. Here, we review the latest cryopreservation methods and applications. We describe the main challenges—scaling up to large volumes and complex tissues, preventing ice formation and mitigating cryoprotectant toxicity—discuss advantages and disadvantages of current methods and outline prospects for the future of the field.

“…37 It has been shown that intentional cavitation induced by a focused, pulsed laser can cause nucleation, although it should be noted that such cavities are preceded by plasma formation, for which photochemistry cannot be ruled out as the underlying mechanism. [38][39][40] A mechanism for NPLIN based on heating of impurity nanoparticles would explain a number of observations that are not readily explained by the polarization mechanism, which we summarize as follows.…”

Results of experiments on laser-induced nucleation (LIN) in supersaturated (S = 1.20) aqueous ammonium chloride solutions are presented. Measurement of the particle-size distribution in unfiltered solutions near saturation (95%) indicates a population of nanometer-scale species with mean hydrodynamic diameter 750 nm, which is almost entirely removed by single-pass filtration through a poly(ether sulfone) membrane (0.2 m pores). Analysis of filter residues reveals iron and phosphate as major impurities in the solute. Experiments show that the number of nuclei induced by LIN can be reduced substantially by pre-processing (filtering or long-term exposure to laser pulses) and that this reduction can be reversed by intentional doping with iron-oxide (Fe 3 O 4) nanoparticles. The use of surfactant to assist dispersion of the nanoparticles was found to increase the number of laser-induced nuclei. We discuss the results with reference to mechanisms of nonphotochemical laser-induced nucleation (NPLIN).

“…Similar thermodynamic considerations should also be relevant for the water-vapor interface during cavitation in the absence of lipids. In this regard, the present study may provide insight into the phenomenon of nucleation of ice during cavitation, also known as sono-crystallization, which has been proposed to explain experimentally observed nucleation of ice at the interface (43)(44)(45). Based on seminal work by Hickling (46) it is generally accepted that sonocrystallization is due to adiabatic compression by shock waves emitted from a bubble collapse and not from bubble expansion.…”

The thermodynamic state of lipid interfaces was observed during shock wave induced cavitation in water with sub-microsecond resolution, using the emission spectra of hydration-sensitive fluorescent probes co-localized at the interface. The experiments show that the cavitation threshold is lowest near a phase transition of the lipid interface. The cavitation collapse time and the maximum state change during cavitation are found to be a function of both the driving pressure and the initial state of the lipid interface. The experiments show dehydration and crystallization of lipids during the expansion phase of cavitation, suggesting that the heat of vaporization is absorbed from within the interface, which is adiabatically uncoupled from the free water. The study underlines the critical role of the thermodynamic state of the interface in cavitation dynamics, which has mechanistic implications for ultrasound-mediated drug delivery, acoustic nerve stimulation, ultrasound contrast agents, and the nucleation of ice during cavitation.
