Artistic Impression Showing Determination of Molecular Structure of the Proteins at Ice Surface (image) American Institute of Physics Share Print E-Mail Caption Antifreeze proteins are a unique class of proteins whose working mechanism is not understood. This artistic impression shows the use of sum-frequency generation spectroscopy to determine the molecular structure of the proteins directly at the surface of ice.
