Observation of Ice‑Like Two‑Dimensional Flakes on Self‑Assembled Protein Monolayer without Nanoconfinement under Ambient Conditions

Caption

  • The two-dimensional (2D) ice-like water layers are formed on the self-assembled monolayers (SAMs), which support the physisorption of Cytochrome C (Cyt C) protein layer under ambient conditions, without the need for nanoconfinement.
  • The morphology, composition, melting, and crystallization processes of the 2D ice-like water are directly characterized using atomic force microscope and nano-atomic force microscopy-infrared spectroscopy.
  • The formation of the 2D ice-like water is attributed to the fact that the activation energy for water desorption from Cyt C is nearly twice as high as that from the SAMs.
