| 논문초록 | Over the last decades, antifreeze proteins (AFPs) have been extensively studied due to their special function of regulating ice-water interfaces. However, the mechanism of their activity is highly debating in the relevant field and thereby there is no generalized design principles of the synthetic analogous of AFPs. In this work, we address this challenge by using gold (Au) colloids as a platform. Benefiting from well-defined shapes of the Au colloids, functional groups are organized in precisely tuned geometries to provide exquisite control over the ice-water interfacial augmentation. From this engineering ability, we show that contact area between ice and antifreezing materials play a significant role in ice recrystallization inhibition. Taken together, we believe that design principles outlined in this work will pave a facile design route toward high functioning artificial antifreeze materials. |
