环境扫描电子显微镜已经被用来拍摄海洋藻类Ulva linza游动孢子分泌的粘附垫，当它们在一系列自组装和接枝的不同润湿性的单层上安顿下来时。水分条件。结果表明，黏附垫的直径受表面润湿性的影响较大，黏附垫在越亲水的表面上的扩散越大（即润湿性越好）。这与以前对海洋生物胶粘剂扩散的观察结果直接相反，并且与三相系统的Young-Dupre方程的预测明显矛盾。在本文中，我们试图从热力学分析的基础上解释亲水蛋白的润湿特性。
The environmental scanning electron microscope has been used to image the adhesive pads secreted by zoospores of the marine alga Ulva linza as they settle on a rang of self-assembled and grafted monolayers of different wettability, under natural. hydrated conditions. Results reveal that the diameter of the adhesive pad is strongly influenced by surface wettability, the adhesive spreading more (i.e. wetting the surface better) on the more hydrophilic surfaces. This is in direct contrast to previous observations on the spreading of marine bioadbesives and is in apparent contradiction to the predictions of the Young-Dupre equation for three-phase systems. In this paper, we attempt an explanation based upon thermodynamic analysis of the wetting properties of hydrophilic proteins.
