Cryopreservation: Synergistic Ice Inhibition Effect Enhances Rapid Freezing Cryopreservation with Low Concentration of Cryoprotectants (Adv. Sci. 6/2021)

In article number 2003387, Hai Wang, Li Song, Gang Zhao and co‐workers have designed tungsten diselenide (WSe(2))‐polyvinyl pyrrolidone (PVP) nanoparticles (NPs) for synergetic ice inhibition based on the hydrogen bonds, absorption‐inhibition, and photothermal conversation effects. The WSe(2)‐PVP NPs can significantly facilitate the high‐efficiency cryopreservation of cell constructs using a rapid freezing method with low concentrations of cryoprotectants. [Image: see text]
