根据Langmuir-Blodgett技术，通过将脂肪酸沉积在固体基质上制备了定义明确的硬脂酸和二十二烷酸多层膜，研究了血链球菌的粘附行为。使用这种技术，并通过调节底物的pH值，它是可能的，以形成外表面组成的紧密堆积的甲基或羧基端基。因此，研究了由甲基端基形成的非极性表面和由羧基形成的高密度带负电荷表面上的粘附性。在实验条件下，非极性表面显示出与参考（金属）相同的粘附程度，而粘附力在具有高负表面电荷的多层膜上被完全抑制。这些结果的意义进行了讨论牙菌斑的形成。
The adhesion behaviour of Streptococcus sanguis was studied on well-defined stearic and behenic acid multilayers which were prepared by depositing fatty acids on a solid substrate according to the Langmuir-Blodgett technique. Using this technique and by adjustment of the substrate pH it was possible to form outer surfaces consisting of either close-packed methyl or carboxyl end-groups. Thus adhesion was studied on non-polar surfaces formed by the methyl end-groups and on high density negatively charged surfaces formed by carboxyl groups. Under the experimental conditions the non-polar surfaces showed the same degree of adhesiveness as the reference (metal), whereas adhesion was completely inhibited on multilayers with a high negative surface charge. The significance of these results is discussed with regard to dental plaque formation.
