贻贝（Mytilus edulis）作为水产养殖物种在经济上具有重要作用，并且在海洋生物污损方面也具有重要意义。它们通过被称为“byssi”的胶原附着线牢固地附着在各种各样的浸没表面上。本研究的目的是表征扩散的深渊附着菌斑，介导附着到表面上，在一系列的表面上的润湿性的变化。为了实现这一点，良好的表征自组装单分子膜的ω-封端的烷硫醇盐在金上使用，允许相关的byssal菌斑扩散与一个单一的表面特性-润湿性。目前的结果是不一致的，从以前的研究中，有一个斑块的大小和表面润湿性之间的正相关性，这是不能解释的趋势，由传统的润湿理论的三相系统。最近扩展润湿理论与亲水性蛋白质进行了讨论和结算试验的结果被用来试图调和这些结果与以前类似的研究，也与最近的数据提出的传播石莼孢子粘合剂。
Mussels (Mytilus edulis) are economically important in their role as an aquaculture species and also with regard to marine biofouling. They attach tenaciously to a wide variety of submerged surfaces by virtue of collagenous attachment threads termed 'byssi'. The aim of this study was to characterize the spreading of the byssal attachment plaque, which mediates attachment to the surface, on a range of surfaces in response to changes in wettability. To achieve this, well characterized self-assembled monolayers of omega-terminated alkanethiolates on gold were used, allowing correlation of byssal plaque spreading with a single surface characteristic-wettability. The present results were inconsistent with those from previous studies, in that there was a positive correlation between plaque size and surface wettability; a trend which is not explained by conventional wetting theory for a three-phase system. A recent extension to wetting theory with regard to hydrophilic proteins is discussed and the results of settlement assays are used to attempt reconciliation of these results with those of similar previous studies and, also, with recent data presented for the spreading of Ulva linza spore adhesive.
