초록:
Water freezing is a commonly observed natural phenomenon; however, ice growth and recrystallization can critically damage living organisms. Nature has evolved to produceantifreeze proteins to survive this freezing threat. Their specific amino acid sequence has been widely accepted to play a critical role in binding to ice, which can result in antifreezeactivity at the ice interface. On the contrary, ice-binding surfaces can also lead toheterogeneous ice nucleation when the appropriate chemical and dimensional constraintsmeet. Ice-nucleating proteins possess relatively large binding surfaces and thus facilitate theorganization of surrounding water molecules in an ice-like lattice that could promote icenucleation. Both phenomena, which require ice-binding characteristics in common, demanddistinct design protocols, and thus active mimetic materials have been developed by tailoringthem for respective purposes. In this presentation, we will address our continuing efforts forcreating the ice-active assemblies that play uniquely at the ice-water interfaces and hence canbe extended to the subzero preservation of bioproducts from cells to tissues.
