Explanation of antifreeze activity of antifreeze proteins and antifreeze synthetic polymers

以碘化银粒子为冰核，研究了抗冻蛋白和抗冻聚合物对冰核形成的抑制作用。结果表明，AFP和AFSP分子不是通过直接影响类冰水团簇来抑制冰成核，而是通过掩蔽银表面的冰成核位点来抑制冰成核。一些合成聚合物，以前不被认为是AFSP，也被发现削弱了碘化银的冰成核活性。

Inhibition of ice nucleation by antifreeze proteins(AFPs) and antifreeze synthetic polymers(AFSPs) was experimentally investigated by using silver iodide particles as ice nuclei. The results showed that AFP and AFSP molecules inhibit ice nucleation not by directly affecting ice-like water clusters, but by masking ice nucleating sites on silver iodide surfaces. A few synthetic polymers, previously not considered as AFSPs, were also found to inactivate the ice nucleating activity of silver iodide.
