Abstract

In article number 2003387, Hai Wang, Li Song, Gang Zhao and co-workers have designed tungsten diselenide (WSe2)-polyvinyl pyrrolidone (PVP) nanoparticles (NPs) for synergetic ice inhibition based on the hydrogen bonds, absorption-inhibition, and photothermal conversation effects. The WSe2-PVP NPs can significantly facilitate the high-efficiency cryopreservation of cell constructs using a rapid freezing method with low concentrations of cryoprotectants.
