An AFM relative stiffness technique was applied to reconstituted Beta vulgaris L. wax films. Consecutive force arrays (n=100) made on the waxy surface at the same locations showed that there was no relative change in surface elasticity and this information was used as a reference to further experimental measurements. A surfactant solution was subsequently dropped on the waxy surface and the same array of indents was made at the same location as the reference test. The plant wax surface showed a reduction in its surface elasticity properties. The study has demonstrated that the AFM technique could be used to undertake a systematic assessment of the plasticising effects of agrochemicals on native and reconstituted plant wax films.
一种原子力显微镜相对刚度技术被应用于重构的甜菜蜡膜。在蜡质表面相同位置制作的连续力阵列（n = 100）表明，表面弹性没有相对变化，该信息被用作进一步实验测量的参考。随后将一种表面活性剂溶液滴在蜡质表面，并在与参考测试相同的位置制作相同的压痕阵列。植物蜡表面的表面弹性性能有所降低。该研究表明，原子力显微镜技术可用于系统评估农用化学品对天然和重构植物蜡膜的增塑效果。
