We have investigated temperature-induced structural changes of N-methylacetamide (NMA) in imidazolium-based ionic liquids-water mixtures by a simple differential thermal analysis (DTA) method and Raman spectroscopy. We found that hydrogen bonds among NMAs in the mixtures are preserved even in the glassy state. Our results may shed light on the possibility of ionic liquid as a cryoprotectant of proteins.
